Well, you've sort of answered you own question. Back in the days of seperate body - chassis construction, a "body off" restoration meant that those two components were disassembled so that everything could be thoroughly cleaned and rust repaired. But an e9 is built differently than a '55 Chevy - you can't seperate the body from the frame because it's a unibody. So I guess the term "body on" becomes the converse of "body off". Admittedly it makes little sense, since it should be obvious that a "body off" restoration can't be done to a unibody car.bfeng said:I wonder what "body on" restoration means for a monocoque type chassis?
