Bought second hand a set of Konis with Ground Controls, and now I also have brand new top mounts from Ground Control too.

But I'm missing what Ground Control calls a 'sleeve', and what's described in the factory service manual as 'damper mounting collar'.

Question - can I use the stock sleeve / damper mounting collar with the Konis? I understand the OE shaft diameter is 10mm, but the Koni is 12mm. If that's the case, perhaps the stock sleeve / damper mounting collars can be modified to fit?

Otherwise, anyone know if it's possible to purchase the sleeve / damper mounting collars on their own?

 

You'll want the sleeve since it'll let you adjust the height

 

I do have the threaded sleeve and collar, I'm talking about a smaller metal sleeve that I believe goes inside the top mount's upper bushing. Any ideas?

 

Koni yellow shocks come with their own sleeves.
Bump stops and other metal bushings should be modified(drilled out) to work w/ the Koni shocks.
If you go into the DIY sticky thread, there's a link to the Koni/Eibach installation.
It'll help you a lot.
Good luck.

Thanks, I'll check it out!
