Multi Part question

The brake system should be fairly easy to address, especially if you are going afermarket disc.... I'd look at Master power brakes, for a complete bolt in kit, that will definately work no problems...... As for the 8.75, if it's narrowed, then you are going to need to take the messurements. Like mentioned above, you can go to summit, jegs mancini pretty much any online auto parts distributor for the perches.
