Boy, are you going to get a variety of answers on this one. However, since you're in KC, you've got two top suppliers withing an hour or so. Pete and Jakes http://www.peteandjakes.com for chassis in Peculiar, MO and Redneck http://www.redneckstreetrods.com/ in Atchison, KS.

Another one is N&N Fiberglass http://www.nnfiberglass.com/ in Bellevue, AR. One of our members (Iceburgh) has one of their coupes. Photos on this thread. http://www.clubhotrod.com/forums/showthread.php?t=23772

Wescott is probably the cream of the crop. They're expensive, but there aren't many (if any) bodies on the market better than theirs.

DON'T buy a Gibbon from anyone . . . ever! Trust me.
