Truthfully, I really don't care what size the u joint is. The truck will weigh only about 2500 pounds when finished, so it's not like it needs a huge one. I wanted the 1410 u joint, because that's what matches the rear u joint in the Dana 70, so, the simpler the better, right? But it really makes no difference. As long as it's a 30 spline and for a Mopar 727 or 833, that will work.
