71 Duster - Previous owner put an 8 3/4 rear with disc front and rear. Rear discs I think are a Leed kit. Front I think might be disc parts he sourced from 73 and up. He mentioned he went with the large bolt patern hubs for a better wheel selection. Also have a Willwood master cylinder w/proportioning valve (1in bore). Since I still have to install the Willwood MC, figure I would put a brake booster on it too. I am unsure which booster to get since the stock MC has a 4 bolt pattern, and the Willwood has 2. Do I get just the Mopar brake booster bracket and a universal booster?

Here is the setup I went with. Worked with Wilwood for booster recommendations.

Speedway 8 in. Dual Universal Power Booster in Black Powder Coat Part # 91664079
Wilwood 261-13270-BK Alum. Tandem Master Cylinder Kit w/Bracket/Valve Part # 26113270-BLK

Why not run manual disc brakes? I'm running Wilwood discs on all 4 corners of my 10 second bracket car with excellent results.
 
I really don't remember, it's been on the car since 2009 with no problems. I was even able to make the next to the last turn off at a track by me that has a very SHORT shutdown area.

I like not having to hammer down real hard in order to stop. Plus it will make it easier for other family members to drive who arn't used to manual brakes.
