I know, this has been covered, but I am a dumass when it comes to search. I have a lione on a mid 70s K30 dually with a blown motor. I am thinking about installing the axles under my 70 K5. I realize that driveshaft mods are required, what about the pads on the axles??? Also, will my manual steer idler arm work? Trying to get an idea cost wise what this will cost me.
