I recently converted my '64 Wildcat to a dual MC set-up and now have this reman booster and master cylinder available. Both work well. The boosters are very hard to find due to lack of available cores. This one has less than 1500 miles on it. Even a good reman master cylinder can be hard to find. I had to return two that leaked before getting this one. Both were purchased from NAPA and I believe were remanufactured by Cardone. I'll also include the SS line to connect the MC to the distribution block. $150 plus the ride from 28716.
