A note about Cherokee disc brake swaps

Well thank you for the tip before i jump on the deal! So I can't get 4" Small Bolt Pattern Disc converstion? Not evene getting the rotors to get redrilled??? Im trying to read up on this but cant find much information.

What about using the A body after market 28 inch axle and having it drilled for a 4 inch pattern. That would give you the same axle spacing as a B or E body axle with a small bolt pattern.
