If you really want a hardtop, buy one, or make one from chevelle doner car. Remove entire firewall section from both cars and swap. Undo front floor seam and cut A pillers, everything comes out untouched as one section. Roof needs to be supported very securely before removal, measure twice cut once. Once installed, factory seams are undetectable, A piller, sleaved, welded and done. Slam on entire front clip from beaumont. Instant Beaumont hardtop
