Hi, not to muddy up the waters any but my son wants to put f-350 dually axle
under his f-250,the problem we are having is the f-250 is a 95psd and the dually rear end is a 97 f-350 the spring perches are narrower then the f-250.
Also the perches are narrower on the f-350 then on the f-250,its as if we will
have to remove the perches off of the f-250 to keep the same spring width
pad. now this info is for the simple fact that i am looking at both rear ends
side by side,thanks

If the DRW rear end was from a cab/chassis it will have a different perch spacing. The pickup versions will be the same.
