I picked up a "79 EC,everything on it is at least 90% except the frame from the rear wheel arch-back. Can anyone help me out as to what other GM frames I might be able to cut and use to fix this? I can't find any other EC frames that are in any better shape.
I could really use the help as this is mommas {baby} and I have to get it on the road.

Only El camino rear frame will work. Where are you at in Iowa.

I'm in Mason City,Would you happen to know of any aftermarket frames/parts available?
