I never knew that the two star-shaped knobs on the outside of the Recaro seats were supposed to have little plastic discs covering the nut holding the knob in place – until I found one in my ashtray.
The disc is marked on the inside with PEKALIT which now translates into “unobtainium” based on my research. I did run across some nice guys over at Benzworld.com who have a need for these discs also on the Recaro seats that were used in the 500-series cars from the mid-80s.
I first tried my “go to” guy for short run molded plastic parts, but these parts were so thin that he had a great deal of inconsistency in getting these made with a urethane mold. I tabled the idea for a year or so until I located a new supplier who could make a fairly low cost CAD drawing, aluminum mold and also cast the parts for me, as well.
The finished parts came in today, and I couldn’t be happier with them. The worldwide, lifetime market for these is in the low hundreds, at best, but I am happy to have these parts and to also have them available for anyone else who has the need.
