Coverting to power brakes

I'm seriously considering updating my 1986 CJ 7 to power brakes by adding a booster , either single or dual diaphragm. My question is, will the existing master cylinder work with a booster or will I have to swap it out. Its fairly new so its a bit of a waste to toss it.

Swap it to one that's properly matched to the booster. I used the duel diaphram Navaho from Off Again Offroad; it works great, bolt-in set-up.

No. They're different.

Power brakes

You will have to change your master cylinder as they are different. There is a machined shaft that is about 1 to 1.5 inches long that goes into the end of the master cylinder plunger.
