Hi, squarenutz, you should install the 3.55 ring and pinion set from Patrick's with the installation kit. Note: there are 2 OD sizes of bushing.On my Canadian 53 rear end it took bushing B. To remove the dowels what I did was drill and tap the dowels and use a small slide hammer to remove them and then on the hole to the rear of the truck I found a large copper pipe that fit in and then MIG welded the hole shut.Note; steel welding rod will not stick to copper. As per Patrick's, I found a 6ft pipe and drove out the bushings. When installing the new bushing I warmed up the end of the torque tube and installed the bushing. The new bushing with seal locates the seal on a unworn part of the drive shaft.
