Thanks Kip, no the ring is the same as yours, the rust was on the inside of the cab where the ring bolts through the sheet metal. The rims are 6 bolt 16" with 11" drums. It was the "commercial" 3/4 variant that has the 14" drums, as far as I know they use the same open drive shaft and rear end (dif) as the standard 3/4 ton. John, I know the larger trucks had bigger opening for the tires, the Canadian Maple Leaf version may be slightly different. There is a picture of Paul Kallens Maple leaf on my site under for sale section. Hope that may help you some.
