This one is by The Right Stuff. By the looks of others I have seen, they all appear very similar and are probably are the same. I cannot speak about how well it performs as my car is a long ways from road worthy but my biggest gripe with it is the large offset bracket that mounts between the booster and firewall. It looks hideous and sets the master out over the shock tower. I did not want to have it look like this so I ended up buying a different firewall plate and did some modifications. By eliminating the offset bracket, it changes the pedal linkage geometry but there is a swivel type linkage available that can be made to work. Also, the studs in the back of the booster are not a direct fit through the firewall so you need to work some magic with the die grinder.... but it will work.
It’s like most “cheap” aftermarket stuff. It works, but gotta be creative to make it what you want.
