anyone have any tips on what the best way is to cutting of the weld on wedges (radius arm c's) of a mid-70's ford hp d44. do i cut directly into the c's or grind the welds away? trying to prep the axle for a tnt truss i recently purchased, also any knuckle ideas? what year and style chevy stuff works, or are reid-racing knuckles the way to go for high steer. thank alot.
