If ORD can't set you up then PM me and I can. You will need to have a couple things go your way for a step-stud repair:
1. The existing factory holes need to be positioned in the center section so that there's enough material to tap a 3/4-10 hole 1" deep. I have seen diffs where there was plenty of room for a step-stud and others the tap would break out the side.
2. You need to have the ability to tap a 3/4-10 hole ...ie...drill,tap,drill press and a small amount of machining ability.
3. You need to know how thick your front spring pack is and if your going to use a Zero rate to determine overall stud length.
Sorry for the high-jack on the ORD sub-page but desertrat67 has been trying to cure this problem for awhile now and I have fixed some locally like this.
