Ribside - I recently acquired an original 1947 Canadian Chevy/GMC Truck Shop manual and a 1948-50 Canadian Chevy/GMC Truck Shop Manual Supplement, which I haven't actually had a chance to delve into yet. When I get a chance I'll try and do a bit of reading in them to see what can be found on your question. wink Can you provide the Model# from the truck you're looking at? It will help me search through the books.

In the meantime, perhaps some of our other Canadian built GMC Owners will chime in with what they know?
