I would suggest Gary or Doug Paine. They live in Ohio. I also have a couple here but one could be blasted clean or I am parting my 71 GS and it has a really nice frame as well. I am in Central PA and am 192 miles from Ohio.
John, I have a 71 Frame complete roller for sale located near Greensboro N.C. Came from a clean Ga. car. Pm me with your email address and I will send pics.
