Thanks for the info Guys! The weather was so nice today (70 degrees in WI) I hit the boneyards with some friends and came home with a NV241C from a 1989 Suburban 2500. So I guess I've started purchasing the driveline backwards...
I did some more work on the frame last night. I drilled drain holes inboard of both main eye spring hangers, and then holes back where the rear of the frame rusts out. I found that right at the bend the frame was very hard to drill through (seemed thicker) and it was much easier a few inched back from this.
I've got the AMC20 with Moser 1 piece axles. I want to say that I was able to use the same rotors as the front. They are 7/8" thick. The older CJ's are 1 1/8" thick. I'll look back at my thread and see if I can jog my memory. Great score on the 44, any idea of the ratio?
I've finished the frame work for now, Welded 4 patches and fixed one threaded insert. Going to coat the frame in Por15 outside and Eastwood inside frame coating inside. Used Metal Prep (Phosphoric Acid, Zinc Phosphate) on the outside & rinsed in prep for Por15 already. Here's what it looks like:
Started with the bottom of the frame first: two coats Por15, two coats Rustoleum black & one coat Eastwood inside frame coating. Next I'll flip the frame and do the same. Bottom took over 12 hours to do by hand.
