Wildwoods and OEM master cylinder??

I'm curious here....I want to run wilwoods dynalite front disc brake kit on my dart, PN 140-11023 but the kit doesn't come with the master cylinder. Seeing as I want my engine bay to look like a stock 68 Super stock car, can I use an original (the correct one for 68 SS cars) manual disc master cylinder with no problems? Or do i need a wilwood master? This may be a simple question but I want to double check. Chrysler PN on the master is 2823576. Thanks in advance! Evan

You should be fine with a stock master, running a wilwood master is not required, what size calipers/#pistons are you running?

They will be the wilwood 4 piston calipers that come with the kit. My dart is a /6 car so I assume I have 9inch spindles. Wilwood offers kits for 9 or 10 inch drum spindles...I can use mine right? No need to upgrade to 10in? I can't see any benefit to larger spindles..

You need the size of the caliper pistons and the bore of the master cylinder.
If they match you're good.

Wilwood lists the piston bore at 1.75. The master cylinder I want to use is Chrysler PN 2823576. I can't find the bore size of this master tho. Google says most manual disc brake mopar masters are 1.03 give or take on year, engine, etc. By my understanding, a master cylinder with 1.75 bore would be extremely hard to push. How close do they have to be exactly? I'll just run wilwoods adjustable master cylinder pushrod and proportioning valve. It's the appearance I'm after with this for my dart.
