Info about tags and rough date of manufacture

Hi all, I recently took delivery of a HK 307 GTS Monaro. Looking forward to lots of research on this forum.

My question, is it possible to find the rough year of manufacture by the build number? Given manufacture went over 68-69 I am interested in registering it with numberplates that match the year.

The plates are Adelaide built in the early 400s of the 80737 series.

I am also very curious to find out if the drivetrain that is in the vehicle was original, I suspect not as there is a butcher job done on the tunnel, and it retains an auto throttle linkage even though a Saginaw is fitted. I am really keen to find out about the engine which I am told is original.

Any hints on where to find any records to match large/small/body/engine numbers?

Many thanks!

here :- http://www.gregwapli... , just under 9000 built of all 3 HK Monaro models from July '68 > May '69 and build numbers are run from 00001 at each build plant so yours most likely a 68 . New price makes me cry !! little over 3 grand for a new 327 GTS !!!!!

It will be a 68 build, late in October or November. 307 engines are numbered by plant so that is the first check.

Saginaw humps are pressed into the floor not welded so that is an easy check.

Also check wiring harness to find if auto or manual.

If manual wiring with butchered floor more likely a 186S converted to V8.

Dates are stamped on steering box, diff, front crossmember and back of speedo. If these items are original then a time frame build can be roughly worked out.

Thanks for the info, I will check it out :)

I believe it has the V8 speedo cable provision in the firewall underneath the wiper motor. There is another grommet (empty but pointing downwards) near the master cylinder. Not sure what that is, and I cannot find any good info or pics around on the firewall speedo cable provision or the other grommet. The hunt continues!
