66f250 front end swap
 

I have a 66 f250 that i wish to install power disc brakes. I all ready have a brake booster and master cylinder from a late 80s f250 installed by the previous owner plumed into the original drum brakes, and they seam to work fine. I belive that a 73-79 f250 twin i beam will swap right in. Is that correct? Another question is will the f350 i beams (73-79) also work?
Thanks, Joe.
