I'm hoping for some help here, I have a 37 Ford that had S197 front disc, and explorer rear disc brakes, with a brake booster and corvette 1 1/8" master cylinder. I'm godzilla swapping it and also had to modifiy the frame Xmember for more room which doesn't provide room for the brake booster anymore. I also swapped in a stock set of 1940 Ford hydraulic clutch/brake pedals.
This leaves me looking for a manual brake master cylinder for disc/disc, I assume a 1" bore, with the ports on the opposite side of vintage mustangs/ford.
