I understand were you are coming from but S&W have been around for a long time, there have been a lot of dart race cars in the past 40 years. Now my friend got screwed by them about 15 years ago when he bought a front frame for a 57 chevy, the rear was already done so we needed from the front bumper to the rear frame. At that time they didn't make frames that long so they just added a foot to the rails, I was really pissed they could have told him instead they just shipped them to us and that is what we got. It wasn't long after that I seen a ad for long rails for 57 chevys and custom street rods. I have bought a lot of stuff from them before that and after and that was the only problem. I built my own roll cage for my 64 barracuda and it fits tight to the walls and the roof, the problem is you can't weld it together and put it in the car and you cant get to the top of the cage, no room so I cut the roof off and welded it back on when I was done. Some things are just easier.
