If you can find a repair manual that describes how to remove the gear stacks, you'll be in business. That's the hardest part of the process, and actually isn't that difficult to do. After that, you remove the diff side cover, remove the diff carrier, and re-install it backwards.

The ring gear, and pinion mesh pattern will have to be checked to make sure they fit together properly, or else they will be noisy, and will wear out quickly. Pinion depth will have to be adjusted to correct it if needed by adding extra gaskets between the intermediate plate, and case.

You'll need the nose cone, and selector shaft from a 911/901 to make it work in a Bug.

I just finished my 914. It is really easy. Just take the front of the transmission off, then pull out the gear stack all in one piece. Put in in the vice to hold it. Remove the side plate. Since you have already removed the gear stack, the pinion gear came out with the stack. You take off the axle hubs on both sides, then you take the side plate off you will see the ring gear facing you. Just lift it out, clean it up and then replace it except you just flip it over, when it goes back in, you now have the ring gear facing down and all you see is the back of the ring gear. Change the shift rod, remove reverse and 1st gear out of the original nose plate and install it into the nose cone, install the dowel pin to hold them in place, install a gasket or two (real important to know how thick this is if they use one or two on both sides of the gear stack, then install the gear stack, put on the nose cone. Make sure you align the ring on the reverse and 1st gear so the nose cone will go on. If you have a good gear stack and syncros there is really nothing to it. Make sure you have a new gasket and seal kit.

Good luck.

You skipped the critical part -- setting the backlash, pinion depth, etc.

I scanned a few pages from a 911 manual and put 'em on the web for anyone who would like to see it. All I had at hand was for the 915 tranny, but you can see the main idea. It's non-trivial and requires some special tools.
