Hi Mark, welcome along, (and sorry for the delay in replying! )
Congratulations on your purchase, has it arrived yet?
There is a lot of poor information online about the Greyhound, but here is where you will find the most knowledgeable and helpful owners, enthusiasts & experts, many with hands-on experience.
There is a good chance your car is an original LHD model(despite various internet sources suggesting only 2 or 3 built, there are 15 'Hounds recorded as LHD), and having scanned the registry I have narrowed it down to a couple of likely candidates, but hopefully you will find a chassis number which can confirm this (if the second letter is an 'X', that's pretty definitive).
Apart from the glovebox, the dash looks pretty decent, the lower section where it curves around the steering column seems to match the top, but it is hard to tell from just the auction photos!
Well, fingers crossed that once you get underneath, your recommissioning is relatively painless, it should be quite an entertaining drive with the 302!
Those of us who have skinned our knuckles under AC's most undeservedly under-rated car are here to help! [8D]
All the best, Nik.
