I'm interested in your delrin spring perches for the rear of the NC:

Can you explain more what you mean by this?
INSTALL NOTES, you need about 3/8th spacer to get the shock more straight so it won't rub the Delrin adapter (and 5mm longer bolt). Depending on the coilover you may also need to look at the sleeve that slides into the bottom of the shock (on our Ohlins the provided sleeve is sufficient).
Where do the 3/8-inch space and longer bolt go? Also, a friend who did his own conversion a couple of years ago told me that the lower top hat lip surrounding the mount for the stock spring is tilted. He had the top hat machined flat in order to fit his adapter. Is that necessary with your adapter?
Thank you for your help.
