Thanks for the link,
I recently contacted HHS to see if my HJ van was eligible for a Vehicle Production Report, luckily for me it was.
Turns out the HJ was sold in June 1975, by Honeycombs in Ayr NQ. Crazy to think that I bought it from Ayr 38 years later.
The most important thing for me was that Ben confirmed that the HJ still retains the original engine.
Ben also mentioned that my car was ordered with power steer and the 3.55:1 diff, performance pack.
Great stuff,
Gaz.
