Alright, well like you I don't have endless time...but I'm interested to help with the project. Depending on the time frame we're talking, a collaboration towards the effort could get something done. If we're looking at a schedule of a couple of months, I've got the time to play around. The bigger challenge is that I don't own a super, and there is typically a lot more going on with VAG strut mount bushings then you might think. I worked on replacement strut mount bushings for B3 Audi's (classic failure part, OE versions last weeks). The strut shaft works on two axis of rotation, not one. Trying to solve the collapse problem resulted in binding with the rotation. Here's the prototype of the B3 unit:
To do this properly would require one of two options:
a) rabbit strut, super strut, rabbit upper mount & super upper mount (so all measurements could be taken, etc) and then ideally a car to view/measure.
or
b) A current adjustable upper camber plate that could be measured and have your custom requests added to it.
