Oh, Man If there was ever a question that I can answer this is the one. BTDT.

You have to put your pedal back together so that you can depress the plunger in the middle of the booster. Make a peice of wood that jambs in between the pedal and the front of your seat to hold the pedal to the floor. Length is critical. Then I used a pair of needle nosed vise grips to grab the pushrod on the engine compartment side. Then it comes right out. You have to loosten the air box so that you can get it out through the little space between the fender and the cylinder head.

I fought with the thing for two weeks till I figured it out with much help from the list. This is not a dumb question, it's one of those Porsche tricks.
