hey guys Im upgrading to Wilwood 4 piston front & rears disc brakes on my A body and was looking for advice on the following:

i. Who is using this setup on a street car? Mine has the OEM
style dust seal caliper that clear 15" wheels.
ii. What disc/disc MC bore size did ya 'all use and how did it
work pedal wise and braking wise ?
iii. My brake pedal has two holes for the MC pushrod, I'm
guessing one give 6:1 for man brakes and the other is for
boosted brakes, which is what the car had ex factory (they
DID come unboosted as well)
iv. I have a prop valve - in which line should I mount it and
where?

Ive seen so much conflicting info on here and other sites that its a joke.

Any tips /advice would be much appreciated thanks fellas...
