Easy. Chopping the top is moderate work by cutting the rood in quarters chopping 2 3 4 in. Out of pillers re weldinf and filling roof gaps being a moderate pain... then theres glass... thats where price is sky high and a giant frustration. I have researched it and havent come across one thats figured out a cost effective eay to do it. Id say if u paid a shop with glass and all ur at 2000 maybe 2500 bucks.. its crazy talk
Chopping the top on any ride is a lot of work= a lot of money! A shop doing it I would guess to be around $4,000 or more ! Body drops in shops are $1,000 a inch here in Calif.
Are you an oopmpahloompah, or do you plan on sticking your head through a sun-roof? Ok, just kidding. I think a chopped top would look cool, but lack of head room may be a issue.
