Okay I have fixed two today so if anyone else goes through this problem. Here is what I found out, there are 2 different size bolts in the housing to compensate for the thickness in a few parts. I called everywhere and no one had correct ones I could find and I didn't want to take a $30 gamble. So I took 4 bolts out of another rear axle by taking the nut loose and leaving the nut on enough to hit it but not mess up the threads. Put them in by starting them and hitting them with a punch and hammer them having a flat washer and put a nut on other side and crank them in.
