1961 cab on 1965 frame

[Sweptline]

I need some information about putting a 1961 Chevy cab on a 1965 frame.

I know that the frames changed after 1962. I understand that the cab mounting point on a 60-62 cab are different than the mounting points on a 63-66 cab.

Who has done this swap and can help me with the specific changes that I need to make? Is it as simple as relocating 1 or 2 frame mounts on the 65 frame to meet the 61 cab?

Thank you all very much.
