I purchased this knowing I needed to make room for the booster under the Floorplan. A few blows with a hammer and I was able to reshape the Floorplan in that area and it fit perfectly. The only thing that may affect some is that the brake pedal lever that runs under the floor board was offset and didn't align with the actual brake pedal coming through floor board. I had to heat it up and realign it to work. I'd recommend swapping out the master cylinder to a remote reservoir one because the master cylinder falls under a floor pan reinforcement. To me it just makes life easier than having to create an access hole to check and fill master.

Pros looks and feels original. The end position is slightly left of the original brake location coming through the floor. Cons. Slight floor modifications are needed to the rear of the floor pan due to the power booster being slightly to big. I cut my floor and added a jump to it so everything clears.

Had my master cylinder on the firewall and had to move it back under the floorboard because of a turbo installation. If it would have a set of instruction on how to locate this setup the fab work wouldn't be so bad. Going to have to make a bubble in the floorboard under drives seat to get the booster to fit. That being said it still a good product.

I would buy again.

Good product, but custom mounting is needed for a custom application. Do not know how it would work in a factory application.

When installing this do I put the front brakes to the back brake line spot on the master cylinder (towards rear of car) and rear brakes in the front spot (closet to firewall)?
