I was thinking about replacing the front subframe from a 1965 300 2dr with a 67 newport 4dr subframe. The reason behind this.. is i can rebuild the 67 sub at my leisure.. and when done.. just replace into the 65 300. Wondering.. besides the odd ball left front motor mount on the 65 and power steering location.. what dimensional differences there are. Is there any frame documentation anywhere? Mounting points etc. I have not measured anything yet, just trying to see if it is possible and what obstacles i may encounter.
