No, they are pretty compact boosters, not the big ones you might be used to seeing. Davey's Jeeps had one for sale a little while back with a good pic, but last time I looked it was gone. Do a search for 95 booster and you're bound to find a pic in one of the threads. You do have to worry about the air cleaner though, there was one for non-power breaks and the pacer style for power brake equipped jeeps that shifted the air cleaner more towards the center of the engine bay.
I have a 77 CJ5 w/ manual brakes and 4wheel disc brakes. It stops fine but I can't lock them up if I had to- I have 35's. I just bought a 90' YJ MC/booster from a salvage yard and bolted it up yesterday. I know it is a single diaphragm but I'm sure power vs manual will be much better, single or dual. Don't get me wrong, I would have gone dual but couldn't find a 95 at the salvage yards.
It was a straight bolt-on, the 4 bolts were already in the firewall-they serve to support the plate on the inside of the firewall that holds the brake and clutch pedal assembly. It does not get in the way with the support rod or the clutch master cylinder (Novak conversion).
The rod fit perfect on the stud on the brake pedal, no need to use a bushing and, it is only about a 1/4" shorter than the original manual MC brake clevis/rod. I'm hoping I don't need to pull it out and cut,thread to adjust it out.
I run a wilwood (from Summit-about $38.00) adjustable proportioning valve in line for the rear brakes, the fronts go straight to the MC - I completely removed the stock proportioning valve long ago and have been using the wilwood valve-works great. I had the same set-up on my 72 FJ40 w/4 wheel disc and I wouldn't do it any other way.
I just want to add, that while the dual diaphragm booster does work better, I have the single diaphragm booster and can lock up 35s if I had to, and I have. The single booster is a large improvement over stock if that all you can find.
