N10 dual exhaust was optional on every V8 in HK-HG except from memory Brougham. HG Premier N10 would be the same optional exhaust from V8 GTS.

Just about every HK-HG was optional as a 4spd manual except Brougham. The only exceptions I can think of are:

4spd not available on HK V8 until Monaro release.
4spd not available with 5.0L in HT until 307 stocks exhausted. There were a few 307 manual HT made by special order though.
HG 6cyl commercial lost the optional M22 4spd availability in HG (either at release or into HG).
I can't recall exactly but there may have been a few engine options not available with M20 4spd, like maybe 161 low compression.
Late in HG availability of M21 4spd was very restricted, primarily as only so many were purchased designed to last until the end of HG, mainly for GTS. This would mean HG commercial V8 4spd post May-June 1971 to the end of HG in 11/71 would be very rare or possibly non-existant.

afaik the XW GT's had smaller front resonators. XY onwards on were bigger. I plan to use a pair of the XY ones on my HK not far back from the extractors, they will be easier to fit as they are offset to one side on both ends.

I've never seen details of any dual systems for HK-HT other than:

HK GTS327 system (was available for 307).
HT-HG GTS350 system.
HT-HG 253/308 system (available for 253/308 elsewhere other than Brougham).

Which makes me remember that the only way you could have optioned N10 on a 307 HT would have been to use a HK system as the HT's system would not fit due to the different exhaust manifold on the passenger side, and even then I don't know if it's clear the HT gearbox crossmember. I seriously doubt any were made though - can't recall ever coming across a factory fitment 307 GTS in HK with N10, so HT would be even rarer.

I just looked at both the HG passenger and HG commercial order forms, and N10 is a valid option on both. Says only on V8 models, N/A Brougham, STD on GTS350. So if you wanted you could easily have ordered a HG 308 Premier, M21 4spd, 3.36LSD Salisbury rear axle (on Premier automatically triggered by the 308 engine and M21 transmission), and N10 dual exhaust. You also would automatically get buckets with console shift.

Reclining buckets was a separate option to fixed buckets. A50 or XS6 were the option codes.

I don't think that the HT Brougham could with the high backed front seats.

When I was at a Austin club of late looking at a 1969-71 Morris 1500 Nomad, they could be made into a bed as well.

Not that bad when you are out on the piss back in the day you could always crash out in the car, it's better than just the back seat. or traveling long distance like from Darwin to Bris, you just have to know where not to pull up and it's better to have a bloody vicious dog with ya as well to keep them undesirables away.

The 807 column was used for to show 807 and 818 parts, an 'A' in the ALL column shows the parts available as option for all other models.

On sheet#3 it shows the front 'pipe and resonator assemblies' 2808619 and 2808620 and the 'intermediate pipes' 2808623 and 2808624 and the resonators themselves 2808625 were available for HK models 807 and 818 only.

On sheet#4 it shows the N10 rear muffler and twin tail pipes were available for all models but the pipe clamps were only for 807 and 818 models.

A couple of mistakes in there I reckon, it looks like N10 was only meant for HK 807 and 818 models.

No, not if you don't have the keys on you.
But that's what it's like is a socialist State, you are not even driving or have any attempt to do so and the bastards can go ya.
