Depending on which calipers you are going with on your wilwood setup will determine which size master you may need. I have the forged narrow superlight's on the front with a bit over 4" of piston area and the forged dynalights on the rear with about 3.5" of piston area. For this setup Wilwood recommended their 15/16" master. That recommendation has been working well for me.

If the calipers you are going with have smaller piston areas, you may want a 7/8" master.

15/16" Black E-Coat - 260-13375-BK

There is also a polished and bare aluminum option. The polished is the same price as the black and the bare finish is about $50 buck less.

These come with the pushrod already installed. You may be able to re-use the clevis on your current power brake pushrod. I would also source an adjustable proportioning valve to plumb into the system. I'm using the Summit Racing adjustable block. It fits the factory line sizes correctly and makes installation a bit easier.
