Firewall holes for power brakes

Hi, I have already asked a little about power brakes previously, but can anyone show me pics of their firewalls to compare where a booster would bolt up to? I got a booster setup from a YJ but am unsure if drilling more holes in my firewall is the best idea.

 

I don't really have any pics, but drilling more holes was the only way we could go when we did it on the 7 project I have been working on.

 

Hi guys, thanks for your help. If you go onto my yahoo photos there are 2 pictures of what I have now:

If you end up drilling, a Uni-bit will make life a LOT easier. Also, if your firewall flexes when you've drilled out your holes, drill out the same pattern in a steel plate to give it a little extra strength and mount that between the booster and the firewall.

by the way, here's a picture of my booster/MC combo... but it as a combo unit from NAPA... it s for an E350 ambulance. It takes up a LOT of real estate but it sure stops the 35s quick.

 

I was reading your post just after i drilled my firewall for my power brake setup, so here are some pictures of what i am doing, seems pretty solid when all bolted up, the center bolts go through my brake pedal bracket on the interior, otherwise i would not have used them, still have to put a boot over the large hole from the orginal master cylinder.

 

What is that brake setup from? Looks new. Just want to compare

 

Hey whatever, whenever you get a chance that will be cool

 

It is new stuff i bought on ebay from fatrodders, it looks to be pretty good stuff but the linkage on the bracket did not line up with anything so I had to do some modifying to make it work, at least I hope it will work, don't have it done yet.

 

woud like some more info on this set up... did the brake pedal match the linkage on the booster ect...

i have the same issue with the hydro booster i got from parts mike... kinda sore about the whole issue. i will prolly go with a stock CJ power brake set up :? good info guys

 

does anyone know someone that has used the YJ setup on a CJ-5? I know most of the 7's have holes already drilled for it, like my brother's '82

 

thanks much
