Hey Bob, thanks for that. I will go look to see if I can find anything regarding passenger vehicles.

Interesting that Ford waited until the last 8 months of production to start this 'matching' process with the AA. If the same applies to the passenger chassis, I should try to find a later (1931) A-4209 print and see if it mentions 'matching' on the print or the EI.
