Series 3 109 ute build date

Mine is a 73' 109 ute and has the complience plate on to of the grill.

I had a look at my spare S3 at the block yesterday and it is a '75 with a compliance plate, but it doesn't describe what type of engine it had, unlike my later one.

Thanks all. Will give VICROADS a call after Xmas and see what I can do with it. At least I ave a chassis and engine no.:)
