I did this swap but bought a booster from JDM. I was able to mount it with the hose connection on the other side like the stock unit. had to take a hammer to the edge by the throttle linkage mount but you can't notice it. They told me I installed it upside down. I'm not sure that is correct but I made it work regardless. I do have an adjustable porportioning valve as well. You do need that for 4 wheel disc setup.
