kelsey hayes c-64 booster rod adjustment

[finz68]

I just received my rebuilt kelsey hayes c-64 booster for my 1965 Coronet 500. After installing, bench bleeding the mc and bleeding the brakes, what used to be a simple touch of my foot to stop the car now requires me to push incredibly hard to get it to stop. I've checked the vacuum line and the check valve and all is good. The company that rebuilt the booster said that I need to adjust the booster push rod length. How to I adjust the rod? Thank you!

That is different than the one in my 64 Fury. My car has the Bendix booster, and the tip is threaded so the length can be adjusted.
