Hey Cory,

Here's something to consider. Years ago when a car was smashed in the front or rear, it was a common practice to cut off the damaged part and weld on another. It was cheaper than straightening the frame and all that body work. Your coupe may be one of those. You can check by scraping off some paint from the trunk interior, the firewall interior, and the underside of the hood. If they don't match, then you may have a refurbished car. There's also the possibility that the frame just plain rotted out and a new piece was welded in. If you're worried about the safety of the welds, have a local welder give you his opinions on it.

Before you go swapping frames, consider the cost, time, and work involved. Nothing fits better than the original if you want to keep it stock. If you want to add IFS, power disc brakes, power steering, etc, then I suggest that you pack a lunch and tape measure and spend the day flat on your back at the junk yard.

That's what I had to do with my 52 Ford pick-up. The frame was originally designed to flex, and after 50+ years it had hairline cracks everywhere. I couldn't find another, plus I wanted to upgrade. It would have cost me thousands to add IFS, power disc brakes, power steering, and lowering. I spend the better part of a day at a few junk yards and opted for a Chevy S-10 frame.

Like I said...Something to consider.

Good luck
