I had to get a frame pulled on my old 68 and the first few shops told me no way without it being complete. I think some shy away from incomplete cars because they are too light. Well thats BS because there are two shops in the OC that will work on it. One is European Motor Car (I have to check on the name, its a friends shop) and the other is Rite-Way autobody in Fountain Valley, they never say no. I dont think its a good idea to just wail away on it or to replace just the last 6 inches. Since I know this car, I truly believe that the right side frame is not only bent in, its bent up, and its pushed back into the fire wall. I would seriously consider replacing the front frame rails complete or take it to a good frame shop and let them strategically pull it into shape. Rite Way charged me $500 to straighten out my 68 and it was severly bent.
