Found my build sheet. Mostly
The registry itself includes 1970 Hamtramck & 1970 LA built cars.
I do list all items in the 'found' section as original items are sent in though regardless of model year / assembly plant because it needs to be done.
It is a financial struggle to keep just those parts going.
So, I do not see it ever being financially possible to expand into registries for other years / plants.
