To my knowledge there is nothing modern that will just bolt in. The space the BTV occupies is very limited which rules out almost everything vacuum operated. Those units that will fit are a bit too weak and located at the end of the pedal, makes it impossible to get the correct mechanical advantage without doing something along the lines Craig has done. Any use of vacuum units in that case without pedal mods requires it to be located further up on the firewall as several have done but also indicates immediately to the purist that the car is no longer stock.

There are a couple of posters who have mentioned using the Electroboost unit from ABS. I believe that is all ABS would recommend as a replacement also. It is an expensive way to go but apparently either will fit in the space or can be hidden well under the floorboard using a different pedal. The additional boost unit can be hidden out of sight & can be adjusted so any mechanical problem is overcome while power is present. Unfortunately unless I missed them, there have been no pictures of installs posted & I don't believe anyone has posted much on the operation. To that end, I would want to know if in original location and something happened to the electrical system and brakes were needed, is the mechanical advantage enough to have decent brakes.
