Rusty , click on the "search" button in the middle of the page on this site you may find some past discussions about that subject that may be helpful to you. Also search the web for articles or "How To Books" on chopping tops. Books A Million may have something also. I don't think anyone can tell you ALL of the details that it takes to do a chop. I know, I've done a few and something new always comes up that you didn't expect or something works out better than you thought it might. Like using the rear glass & frame from another car that may fit & look good without the exspence of having a custom glass made. A good imagination always helps.
