Found the real issue. The two bolts tha tcome from the top through the angle bracket actually thread into the upper half of the rear housing. These two bolts were sheared flush. So I pulled the rear axle and drilled out the broken bolts and actually installed heli-coils. I'm going to use studs and loc-tite them in and use nuts and lock washers to fasten the axle to the angle bracket. Piece of cake. I also notice the two flanges on the frame where the acle bolts to is all but ripped off. It seem the axle was rotating forward and backward without the broken bolts and tore the sheet metal frame. So I'll weld them up tomorrow and back it up with some 1/8 thick angle iron. After that it should be solid as a rock again and the rear axle should not rotate fore or aft.
Thanks,
