Which brake booster to use?

HI, I'm pretty new to the site and from what I've seen I love it already! I just picked up a 1982 Cj8 to add to my collection. I'm doing a full resto on it and was looking at the brakes today. I have no-power brakes and want to change them out to power brakes. I have seen adds in JP mag. for power boosters from other vehicle that fit in jeeps to help stop them better. Have any of you done this? Or should I just go with a stock power booster out of Cj? Any help would be great. thanks Dan

If your running 32 inch tires or under, I would stay with the stock power unit. You will need the firewall bracket, the booster and master all together.
Folks are always trying to swap in the YJ booster, but forget that the throw of the pushrod is different and the pedal pivot point is moved....IF mix matched, this results in low pedal or soft brakes. If you swap, swap all of it.

I have a YJ setup in my CJ 7 and like it. I bolted it up without lengthening the rod and the pedal is very soft. They work very well but very soft. I will lengthen the rod at a later date. Easy swap. Very good upgrade. I am running 35's and I can lock up my tires on dry pavement.
