Anyone know where I can find these, or know where I can find specs (i may be able to get them machined for me with a spec sheet) ?

 

Protege Garage was selling gauge rings made by the original Dave B himself. Fairly reasonably priced too. I just checked their site and didn't see any, you could give them a call to see if they have any. I believe that SLS was also selling them, if not you will just have to try and get a set off one of the forums.

 

SLS? Link?
