I have a 10 bolt 7.5 rearend I am thinking about putting in a ford 9in. If I put a 9in in I will notch my frame rails and minitub the car. What is the best way to go about doing this. It looks like I can buy a bolt in housing from several different companies for around $400. I also know somebody that has a 9inch that is the correct is a 1/2 short in width and has weld on kit for g-body and they want $200 for it. However, I am thinking that I will need a jig to weld it up correctly and I will have to modify the axle tubes and buy or respline the axle shafts because the ford center section is offset different than the chevy? How much would an axle shop charge to modify a 9inch to fit a g-body if I supplied the core. Because I would like to reuse my friends center section and gears and possibly the axle shafts. I am trying to do the switch as cheap as possible any advice would be appreciated. Is there any 9inch conversion how to out there?
