so im sending the car to a shop next monday (Jose's Rotary in Louisiana) to replace one of my rear differential bolts, which if you dont know is hardened and molded into the body. as well as a new axle for the one i snapped along with the diff mount bolt.
what im asking is what is he going to have to do to replace that bolt and what do you think im going to have to pay for him possibly having to cut into the body and such to properly get to it, if he had to do that.

 

The major part of the bill will probably come from manhours rather than pieces so it is impossible to make an accurate estimate. Being a specialty shop they might charge a bit more then other garages though.
