This will help with some part numbers:

Give Karmann Konnection a call, and order the Stoddard Porsche parts catalogue, the shims kits etc. can be found there.
Applogies if I'm being a bit vague and confusing

, it's a bit late...
Have a close look at Glenn's site, particularly the part numbers in the pictures, and then look in the Stoddard book.
All the best
