Oh I read them. I just am having trouble understanding why you are not comprehending it.
1. The auction states the VIN. Obviously a 1969 Swinger 340.
2. The car has the " MATCHING NUMBERS BLOCK". This does not mean the displacement matches. It says nothing about the transmission. It says nothing about what car it is out of. It is a generally accepted term in the Mopar world starting in 1969 (some 1968s as well) that the VIN stamped into the engine block matches the VIN on both the dash and the body locations.
