The other rail problem was in the rear where the aftermarket exhaust had all it's weight on the tailpipe hangers after the crummy, universal hangers that were sheetmetal screwed into the rear bulkhead, ripped out. It appears that the reinforcement section of both rails were not properly tack welded in originally, as the pass side area pulled away and cracked the frame under the panel.
