Hoping someone can help me out , I Have the stock enclosed diveshaft and rearend in my truck and need to change the spider gears and side gear, does anyone know if the Canadian trucks ( 1300) and the USA trucks (3100 ) have the same size spider gears and side gear ? or how many splines are on the end of the US model axle, I know the carriers are different because you can not use the patrics ring and pinion set on Can truck because of ther different carrier, thanks guys and this site is awesome and a real help with my frameup restoration . Mike
