Tony, I don't know why anyone would want to hack up an orig frame on something that was as 'modern' as '64, unless you were building a drag truck or something. The IFS is just too darn good on these trucks for street use, and you can get polyurethane bushings for everything on the susp. Judd's right about the parts trucks, dime-a-dozen here. Rotors are $9-$15 at any auto parts store.
Hey, Judd! Small world! I'm from Irvington Al, which is about 45 mins from Biloxi!
