So I have a '67 F250 that has drum brakes and would like to swap to disc. I also have what appears to be a late '79 F250 rolling frame. I'd like to swap the whole I beam setup from the '79 frame to the '67. Upon further inspection I see that the '79 frame has a different style of radius arm and bracket. I assume I cant just put the I beam / radius arm combo on the '67 as the brackets for the radius arms are different? What do I need to do to make this work with what I have? Or do I need to find another donor? See pics below...first pic is the '79, second is the '67.

F250: The radius arm brackets are 1979 only, the radius arms are not. 1975/79 radius arms depending on the GVWR (there are two types) are different than previous years.
If the frames mounts are the same width apart on both frames and both RAs have the same overall length and same diameter and length bushing shaft at the frame end it should swap right over, just use 67 style bushings. Worst case scenario you'll have to swap the RA brackets from the 79 frame to the 67 if the RA lengths, or bushing shafts, are different.
Radius arm and bracket differences??
and bracket.
