Chingon, What I did when trying to decide how much to have the top chopped in my '32 was go to a large car show and look at different examples. By doing this I changed my mind on how much to chop. But now I see that everyone {including myself} still hasn't answered your question! Quote "how much should I pay to have my top chopped 4"?"..... Sorry I don't know how much, but I know a guy who chopped his '31 3" and he said it was easy......
