Needing to do all the u joints on my 7.3. I'm wanting to use the Spicer u joints. So far what I've gathered is 1350 on the front drive shaft and 1410 on the rear, I have found the ones for the front axle. Does anyone have any more knowledge on this? I'm not really finding the same info in any 2 spots so I'm hoping someone on here has some insight.
