Hi all .. i'm going way back in the memory bank, but i think the early HK 307 cars were Powerglide automatic only because of the problem of having the aircon option... which i think had the requirement of a having a bench or bench/bucket with column shift seat arrangement ?? (dealer fit aircon ??)...
...i'm pretty sure the manual floor shift cars with buckets precluded having aircon as an option, so the four speed floor shift cars were a very strict order, and mainly i guess for those specific, early 327's..
...please correct me if i'm wrong ...cheers fellas
Yes, the early days of HK options were very messy indeed. In pre-Monaro days there were no console shifts of any type & no Saginaw manuals. You had either 3-sp column manual (all-synchro optional) or Powerglide (column only) & the long stick Opel 4-speed on the floor behind 6-cyls only (in sedan/wagon only).
Basically when the HK was first released the V8 was Powerglide only & the a/cond was V8 only but not with discs. The new 6-cyl head casting to mount the a/con came along around the same time as the ute & van release (Feb 68) but you still couldn't order V8 with discs AND a/cond together, you could have one or the other. The simple fact was that the brakes pipes exiting the m/cyl fouled the compressor, whereas on the drum braked version the m/cyl was miles away, back on the firewall.
Several 'fixes' were tried unsuccessfully, but things came to head when the Monaro & Brougham were released because you couldn't order a/con with the V8 & front discs were standard on Broughams & V8 GTSs. The real fix came with the new booster (without the relay levers) which placed the m/cyl away from the compressor on V8s.
The Saginaw was a relatively common (although expensive) option, but you could now order a 4-sp manual (6 or V8) in a ute or van, post Monaro release.
I believe that GM-H 'got caught with their pants down' with option availability in the HK series, they simply allowed too many options to be available on every model. Talking to ex-GM-H factory guys from that era, they tell me stories of half-built cars sitting round clogging up the line, awaiting particular parts to complete that car. They often over ordered option kits for ones that didn't sell & under ordered on option kits for those that un-expectantly sold very well.
I've seem some very strange combinations overs the years. A friend had an HK Kingswood sedan optioned with a 186 Powerglide, power drum brakes, power windows & power steering, but no radio or heater !!
