Good question on the frame and body parts thing between the Canadian GM cars. I've only known about the Canadian Pontiac combos, but never thought about the other divisions. Would be interesting to know, just out of curiosity. Mark l
Gm often got rid of parts they were making obsolete on American built GM vehicles by sending them to Canada to be incorporated into the net year's Canadian models. Usually nothing wrong with the parts, but often they were mixtures from different GM models, unlike the US built equivalents.
I had a friend who had a Canadian Pontiac that we scrapped out, and it was fun to see things mixed within that one car.
