67 cab on 64 frame

[Txllstep]

I had a swb 64 frame given to me and want to put my 67 body on it. I only have the body....no frame. I see threads about putting earlier cabs on the 67 frames but not one specifically for what l want to do.
lm sure that it should fit if the rear mounts and bumper brackets are the only change if you wanted to put the earlier cab on the later frame.
Swb 67-72 frames are hard to come by and command a high price when found. My frame is already converted to 4 wheel disc brakes and has a built rear end.
What do you guys think?

I'm no expert but I believe it's really close just slightly differently where the core support bolts on

Thanks, lm hoping there's no big issues. I know the title needs amended but lm not worried about that part.
