Our Cal Spec came with the 2 rods that go from each hinge. I don't know if these are the hinges for our car, but what we have. If you have those, no worries in taking them off. Losen both bolts on each side and they will come off together. Eventually, after you get them out of the car, they will come loose and come apart from the hinges. Putting back in are alittle harder, but okay. I would wear gloves.
As you can see on our gallery, we completely dismantled what was left of our car, put the car on a rotisserie, and sand blasted everything using a borrowed sandblaster. If you want more information on media, let us know and I can get PBgt/cs to respond.
Our car started as a mess. Alot of rust, after sandblasting, we used POR15 on the front clip, primer on the body, then flipped over and started cutting and welding.
Hope this helps
