Well, I got the 14 bolt Full Floater under the truck now, only issue is the parking brake cable, its too short, oh well. but I have another question, Since its bigger brakes, the rear locks up really easily and I have hardly no front brakes because I can't apply enough pressure before the backs lock up and it goes into ABS mode. I have heard that a duramax mastercylinder will bolt up to the truck and work fine because of the internal prop. valve, would that fix my problems, or do I need to add a prop. valve at the rear of the truck.
