Gotta friend who is looking for a high quality chop job for his '32 3 window coupe. He's in central Iowa, would like to keep the work in Iowa. Checked the Hamb-o-dex, nothing really popped up in there. PM me with pics of your work if interested.
Who owns Z Z Shop? I don't know if he'll do just a chop job but you won't find anybody better than Dave Lane: www.fastlanerodshop.com
Dave Lane is the guy to do it. It might take a while before he can fit you in, but it'll be worth the wait. That's not a car I'd hand over to just anyone. Pay the money and take the time to get it right.
I know it's not Iowa but what about Kenny Baker aka Choprods in Elmer MO, not far from the Iowa/Missou border. http://akathechopper.tripod.com/Index-2.html
Scott Schnikloff (spell?) in Manly. Genius metal bender. Scott's doin' a 57chevy Ridler car that's "EFFIN" not Real. A 32 chop would be a break.
I second it hes the guy to go to chopped more tops than anybody check the web site I know Roger Ward uses kenny
Dave Lane would be my first try. He's a friend of mine and has a long waiting list. Mostly all full builds. If its just a chop and no more he might be able to squeeze you in.
