ok guys i got it now,the only thing that i dont know if all 12 bolts rear ends are the same(gm) ? or the cars are different to the trucks?
thanks for the advice.

Well 64-67 are the more desireable ones to me, 68-72 are 1" wider. The truck 12 bolts i forget how wide they are but the pinion size is the same as the 7.5 10 bolts. So as they are a 12 bolt to me they aren't as strong as the car 12 bolts.

The truck 12 bolt will not have the upper control arm mounts (ears). Same for some other passenger cars. You need one out of an A-body, such as a Chevelle, etc. that has the 4 link setup.

Keep in mind if you go with a 12 bolt from a 64-67 chevelle you will also need to have a rim with a back spacing of 5.5 assuming you are running a 275-60-15. And the iceman control arms will fit perfectly, thats what i have.

here`s the story ,maybe i didn`t make myself so clear,the thing its that i need the jig fixture because my 12 bolt rear end doesn`t have the upper ears ,ts from a pick up truck and not from a car ,thats why i don`t need the relocation brackets,i need the jig to make the whole job done.
hope anyone have pics
thanks
