G50 Parts??

Using a '94 G50 and was wondering if anybody knows a source for a throw-out bearing release fork. I found one at Patrick Motorsports but it seems a bit expensive at 200.00 for the arm and pivot kit and then another 67.00 for an updated guide tube.

The dealer wants 150.00 just for the fork.

Another question what diameter is the stock Porsche clutch master cylinder? Found a slave but need to run an AM master cuz there's no room.
