Huge thanks to both Youngster and tfeverfred for the replies. I've decided to weld up my own frame using the CCR chassis plans because I'm up in Winnipeg, Canada and shipping cost for a steel frame would be thru the roof.
I'm glad to get a good word on MAS bodies since Minneapolis is just a punt away from home. Seems to be a lot of good component suppliers out there - Total Perf, CCR and Speedway.
This fiberglass body thing is new to me, and it would be greatly appreciated if someone can give a few tips on wood re-inforcement.
