Hi Bazza , I have a JL434455 last number may be 6 or 8 engine that came out of a 5/73 GTR can you tell me if it is a GTR motor ? It is under other stuff and up against a wall , so I can't get at the date code
G/day Bruce
I know my name isn't Bazza, LOL, but I had a look at the vin listing anyway. Couldn't find your engine number (or alternative ending variations) listed for either Brisbane or Adelaide however recorded engine numbers around yours would suggest it could have come from an 11/73 built car.
Bazza may have a better chance of finding it but I can't.
Cheers
Dave.
