what is wierd on these truck is that they have the same end caps as on the newer 3500hd's.meaning the end cap that holds the axle on the tube has five bolts and so doesmy 70's chevies.but the actuall center section is HO72 and the newer is dana 80.which according to rock climbers is a junk rear meaning they brake easily.my uncle who is a x-machinest for KRUPPS in germany says if I can get 4 rims he'll machine a plate to weld in and should work.so now the 2nd question where to get 4 rims....know of any for sale grigg
