We had to make a few things to fit the GM Hydroboost along with the BMW master cylinder.

We could have used the GM master but also wanted to keep things as stock as possible (I know right...we are installing an LS in an E12, stock?!?!) we used the stock E12 master.

This engine (6L truck engine) also got a small cam and required some custom brackets to move the alternator.

There are MANY more pictures of this swap down in the gallery. I can only post and remember so much about these early swaps.
