Lightningtruck,
You may also check what big brakes you have. Some of the Canadian market brakes where different. I'm not a huge expert, but I believe one of the differences where how many bolts hold the drum to the hub. I make a disc brake conversion kit and one of the kits I shipped did not work on the canadian market truck due to 5 bolts holding the drum on versus the 6 bolts for US market.
Hope that helps a little bit,
