In a nutshell, If your KH knuckle already has the ball joint attached, remove the drum brake knuckle from each ball joint and substitute the KH knuckle. As others have said, now is the time to do the UCA bushings and ball joint and LCA bushing
Dartman, a long time ago when i was thinking about doing this, i read somewhere that all you have to do is drill out 2 mounting holes to the next size or something but i do not remember how this went. Like i said, the KH setup i bought already has new lower ball joints with them, already bolted to the knuckle and all. They were sent to me ready to bolt between the upper and lower arms..in the guy i got them from rebuilt them all, then decided he wanted bigger brakes. He unbolted them from the upper ball joint and lower ball joint and sent the assembly to me.
