I don't have the truck at home right to look, should I expect to find a tag on the rear with a code for the gear ratio? Will 4.57 gears from a '63 one ton swap into the '62 housing using the '62 axles, etc? | | | | | Joined: Nov 2002 Posts: 1,002 Shop Shark | | Shop Shark Joined: Nov 2002 Posts: 1,002 | The pumpkins should swap. I vaguely remember something about splines. The 3/4 tons used an HO52 and the 1 ton an HO72. You should find model, ratio, etc., stamped in the axle housing to the left of the pumpkin. This question comes up often, so do a search for Eaton and see what comes up.
