I got a 14ff with disk brakes, that i want to put on a 71 blazer. the ubolt kit that Off Road sells, can it fit the 14bolt, with a 2 inch lift block? Can i still use the emergency brake with the disk brakes? Do i need longer ubolts if i where to put the 1 inch block on the front axle? i think this is all i need to know for now. thank you.
