Hi Lynn, I know why this post is confusing..... I posted part 2 but not part 1.

Part 1:

I am sorting out the driveshaft this week. The new heavy duty unit is made with 3.5” OD 0.084” wall thickness tube (steel so it is PSMCDR compliant) 1350 U joints, (the rear u joint is half 1350, half 3R) Spicer 27 spline slip yoke. The DS is the same length as original but the SL is much bigger in a few directions and the SL shaft has a step that the original didn’t have..... maybe the DS is too long.... I knew I have to shorten the SL so that should be step one then I can get proper measurements.

I added some measurements of inside the SL and how far the trans output shaft sticks out the back of the trans.

PS: I installed the original for prom as the new HD DS looked too long, now I am getting this sorted out.
