Since my original Dana 20 is "wore the heck out" and a bungy cord is now needed just to hold it in 2 wheel high, it was time to rebuild or upgrade the TC. I found a good deal on a built Dana 300 that has all new bearings, twin sticks, a 32 spline heavy duty rear output, and a JB 4:1 low range kit. I figured the last weak link to the 300 was the front output so I will do the slight machining to the aluminum bearing housing and install the heavy duty 32 spline front output shaft.

I was surprised at the huge difference in the size of the new 32 spline output shaft as compared to the OEM output shaft.
