Mercury car frame swap
 

Hi everyone. I have a 1966 mercury meteor with a rusted out frame and I've been looking into getting another one for it but so far all the frames I've found have been just as rusted. I'm wondering if anyone with a 1965-1968 full size mercury car has replaced there frame with a more modern frame and how much fab work it took if they did. Thanks

Or if anyone has the dimensions/specs for the 66 frames
