Looking for a set of rings for the standard 911T 2.2 liter 84mm 1.5x2.0x5.0. Received a set of Deves Rings, but customer hesitant to use due to comments about smoking. Anyone with a set NOS Kolbenschmidt Rings they would be willing to part with. Any other recommendations?
Thanking you in advance for any leads.
