Ok I thought about this and I'm just wondering how difficult it is to do. Say you have 1/2 ton running gear (1/2 ton IFS w/ six lug and a sf 14 bolt) how hard would it be to put in 1 ton axles (1 ton IFS w/ 8 lug and ff 14 bolt)? New knuckles possibly? New driveshaft? What would kind of work would be required to make that work?
