Bugged,
Yes, our shifter is designed to work with the 901 dog leg box..
Here is a link to an older thread.. at work so can't check to make sure my old video is still up.. but Martin goes through the first few gears..

From you sig name, can't recall if you emailed me.. But if you haven't email me, as I have a ppt, that answers your second question.. but the short answer is yes you use the bug shifter, which is supported upfront by the shifter housing on a bushing.. at the back end, you have a few options such as cut and use the back end of a porsche shift rod. This is splined and will mate to a porsche coupler.. which attaches to the box..
Shifter is approx $420 US

at current exchange rate.. lot of good feedback from the european market from both beetle and porsche owners.

Enjoy,
