If you go with factory stock stuff, it should be a simple bolt in. The holes for the frame brackets are already drilled, or they have been on every E-body I have ever seen.I added a rear bar to my 71 Challenger,and it was a bolt in. I took all the stuff off of a 73 Cuda,cleaned it up and bolted it in. I used the original u bolts that were on my car, and they were plenty long enough. It handles better and I didn't notice any difference in the ride. It's an E-body.....how could you tell?
