Just thought I`d show you all what I`ve been up to today.
I have a booster and master cylinder from a 1986 audi 80. It is much bigger in diameter than the golf one and the master cylinder is less bulky.

It has a collar which connects it to the audi, with four bolts bolting it to the booster and three bolting it to the car. If I remove this collar, it should match up with the golf studs and fit up to the brake rods.





As you can see, i got the collar off. Now to match up to the golf bracket.



The audi booster has a longer arm, but it has a thread on at the same point as the golf one. Now if I can undo the rod, I can mount it up....

Easier said than done. Won`t shift. I`ve soaked it in penatrating oil and will try again on the morrow...
