As far as i'm aware there is only two basic variations: M21/M22 4spd and the rest. The holes and different bosses for the different kinds of floor or console shift for 4spd or powerglide were cut and added later. I think the inner bucket seat brackets were too. Salisbury diff cars had the panel with the clearance hump but that isn't really floorpan although I guess you could view it that way.

I deleted the other identical post over in general discussion too.

Lots.
Split it up into the two pans, front and rear, and you have:

Front Pan - 5 variants:
1/ Bench seat - LHD and RHD
2/ Bucket seats + Opel gearbox + No console - LHD and RHD
3/ Bucket seats + Column shift - LHD and RHD
4/ Bucket seats + Opel + Console - LHD and RHD
5/ Bucket seats + Saginaw gearbox + Console-LHD and RHD

Rear Pan - 4 variants
1/ Wagon with Banjo
2/ Coupe and sedan with banjo
3/ Van and Ute with banjo
4/ Salisbury

Which gives you 40 combinations, 20 LHD and 20 RHD, if you assume that combinations like opel gearbox + Salisbury diff, utes and vans with buckets and floor shift etc etc are possible.

How many of these combinations were actually built, who knows?

I didn't regard the shifter holes as different as they are cut later, and there is 3 x HK Opel shifters that there are at least 2 x different holes for. Same with console and seat separator screw holes (eg 4spd ute front floor will be the same floor as a V8 4spd sedan but no console holes).

You couldn't get Opel with Salisbury but you could get Saginaw with banjo.

Terry, I addressed the specific question in the initial post, but I think Byron is essentially correct, at least as far as the front pressing is concerned i.e. there were two main pressings, one with the wrinkled mess on the tunnel for Saginaw gearboxes (sorry, M21/M22), and one without.
In fact, 1/ and 2/ are the same part number, indicating rework on the factory floor to gas axe the hole for the shifter after the pan was issued to production.
I'm assuming the LHD/RHD differences would be the accelerator pedal bracket and dipper switch attachment. (That, and more foot room - the HK/T/G is a better LHD car than a RHD car!)

The front and rear pans are two distinct items, joined behind the second transverse brace.
I'm not familiar enough with utes vans and wagons to know all the differences, but the way the part numbers are structured you would think that Salisbury in a wagon ute or van was not an option. Do we know differently?

The situation with HT is different, as the front pans have been rationalised to 4 variants, with the first two sharing the same part number. The rear pan is a very different story, with 7 variants. The part number for the rear pan for the HT81837, for example, is unique and not shared with any other model.
In addition, a separate pan is listed for sedan, ute, van and wagon to suit a Salisbury.

Controlling the bills of material, inventory and specific production instructions for all the variants in the days of manual document control must have been a nightmare.

Byron, I think blameyone might be just poking us with a stick to stir us up a bit.
All good clean fun.

Yes, it is confusing the way that manufacturers allocate part numbers to their various assemblies.

It seems to me, from a layman's point of view that it would be easier/simpler/cheaper to just keep the various pieces required for replacement purposes. One also wonders how many floor pans that they are likely to ever sell.

In the case of HK/HT/G floor pans, there are 4 basic pressings, 2 front & 2 rear. All of the variations are made up of the various add-ons or cut outs. There is the hole cut for the console shift, where a 'blister' mount is then added. This would be needed for all Saginaws, Opel console shifts & all T-bar autos. The 2 versions of the non-console Opel require a hole cut further forward & all column shift cars have no hole. The accelerator pedal mount for RHD or LHD is another add-on. All other holes for dipper switches, centre consoles or seat separators etc. are simply drilled as required.

Bucket seat cars get the extra mount strip & holes toward the tunnel.

There would only one front floor for Saginaws because they all had bucket sets & one shifter type, console or not.

AFAIK it is possible to option a Salisbury in a wagon ute or van, but AFAIK the only other add-ons would be for things like wagon fold rear seat hinges s etc. However the same basic pressing was used for all cars (except for the hump).

Dr Terry

Do you mean with bench seat Terry? I was referring to only HK, and console shift M20 post HK Monaro.

HG is a weirdo. 8/70 order procedure for HG passenger vehicles states that M11 is mandatory with M20 if A55 or XS6 specified (which is the same as HK post Monaro release), BUT says N/A on Belmont. Which indicates that you could specify a HG with M20 but no other options ie bench with hockey stick. However you had to have a console with M20 and buckets and only on Kingswood. The order procedure also says that D55 (seat separator) or M11 (console) are mandatory with A50 buckets, but then notes M11 N/A Belmont - therefore A50 comes with D55 on Belmont. But then says M11 is mandatory with all when A50 or XS6 specified.....but N/A Belmont.
However if you read the HG Kingswood passenger sales brochure PH96 dated 7/70 (which for some odd reason also contains HG Belmont passenger vehicles) it says for Kingswood you could get 186 and 186S with 4-on-the-floor (with or without console). It then says "Holden Belmont Sedan and Wagon are the same as for Holden Kingswood except that transmissions incorporating a floor console are not available. A 4-on-the-floor gearshift without console IS available with 6-cylinder engines. NOTE: Bucket seats are required with floor console shifts". The custom features chart then says that A50 (fixed beckets) are YES on both Belmont and Kingswood, and Kingswood also can have XS6 (reclining buckets). The IS as typed above is capitalised.
So what is confusing is if you read both the above documents they both say M11 console shift not available on Belmont. Both documents also say A50 is available on Belmont. Yet the sales brochure says M20 IS available without console. Nowhere is there mention made that if you wish to order M20 on Belmont that you cannot order A50 which is the only way all of the conditions detailed in both the order procedure and the sales brochure could be met? I just find that odd, as all through these documents especially the order procedure they are very specific about what you could and couldn't order, and what conditions were applied if you did tick a box (like D55 or M11 mandatory with A50).

HK Powerglide 6cyl and V8 are the exact same body (except for GTS which after late July '68 gets a Salisbury and rally rims, so diff hump and spare wheel brackets). The V8 speedo cable hole is sawn out of the body later but they both have the 6cyl hole.

You'll very rarely find mechanical combinations that aren't normally orderable. Primarily as maybe 75%+ of all vehicle are stock orders ie vehicles built by GMH for sale as opposed to ordered vehicles. The vehicles that were ordered sometimes go out of the box a little. The rarities that break what is normally spelt out in order procedures or selling manuals are either styling or otherwise internal cars, or cars ordered by people who knew how to use the "special instructions" section of the order form and/or knew how to sneak it (or brute force it) through the zone office. Examples are cars like Bob Jane's L30 M41 HQ Premier wagon.

There were some things that unless they were built as internal cars by Engineering or styling, you could not order on a regular production vehicle. Stuff like fluted guards on vehicles that didn't have them standard. Yes lots of people "got them by special order", but what they were never told was the dealer fitted them for them.

An example of a combination that you could order readily was a HK 6cyl passenger vehicle with a 186 and M21 4spd. However as far as i'm aware only one has ever turned up, an early HK GTS.

All panels were pressed in SA and freighted to each assembly plant. I doubt there would have been much stock left at the end of HQ as the bonnets would simply be used on HJ cab-chassis. The assembly plants only kept stock for a week's production and all parts were sent to the assembly plants based upon the schedule.

In the HQ-WB range many GMH people were able to get their lease cars done to order with options, extras or double dipped in chocolate as there were long term friendships etc.in the plants and offices. GMH staff discounts often saw the vehicles returned for sale through their own in house sales team as they were changed over for later models. This process stopped about VS as cars now go through the dealer sales. This resulted in some vehicles being over specced or specially made for family and friends. Often the dealer was not aware as they only did the paperwork and collected a sale fee.
