Have to put a new transmission in my '51 GMC 1/2 ton long bed. It presently has a 3 speed but I was wondering about a 4 speed. I have heard that you need a different u-joint for the 4 speed and there are abit hard to find. Since I have a a long bed and I have 2 u-joints I was wondering if I need t replace both or is only 1 that is different?
Any preferences between the 3 and 4 speed?
