I have a question about putting a cage in my 85 cutlass. I am going to cut the floorpans with a plasma cutter to the frame to weld the cage in then cut the pieces of the floor to fit around the bars to be welded in place. My question was about the body mounts. Will the points where the roll cage is welded to the frame replace the body mounts or do i need to buy solid body mounts to compliment the cage?
