OK.
The calipers for the 1998 K2500 with six lugs are the same as the K1500. Same part number. The K2500 with 8 lugs has a different size caliper with a larger piston. That means to use the larger caliper, the knuckles must be changed.
The JB5 drum is 10". the JB6 has 11.1" drums and the JB7 has 13" drums. So an axel change is what it would take for that mod.
I might start looking for a used 2500. I don't want to do all of that work in the timeframe I have to get it done.
