I know of a large wrecking yard in California called Turners auto wrecking
And another one up In Saskatchewan in Clavet called Amigos auto wrecking
Both have these old trucks and a selection of old cars with the same engine.
If there is not one already
This forum might benefit from a specific topic or section about known wrecking yards and their location with the latest information from bolter visits
I think that would be neat.
