Chad,
If you decide to go with a narrowed rear.
I have 2 Moser built, one still in the boxes.
Truck rears (8 3/4) / re-splined axles, green bearings. set up for 10" wheel / 5"back space
I ended up going to a Dana.
whats up Howard!! I didn't think you were still around, aint heard from you in a while. Man I need something to get some meat back there..want to fix it up for me?
