This was tonight's doing.
Picked up the new rear center section from my friend that ordered it for me. 31 spline axles, Detroit Trutrac with 4.11 gears. We got that installed tonight.
Please don't mind the red silicone. My friend likes to use it all the time.
Letting it set overnight. Will fill it up in the am and let the gears break in.
Hopefully will be done finally and can start to put miles on it this weekend.
