I have been working on some replacement throttle pivot bushings that are similar to the originals (with a few tweaks) and I am finally at a point where I can reliably produce them.

Have a few people trying them out, one driving many miles a day without issues.

Still working to perfect them cosmetically, but each has been tested in an actual w123 mount to be sure of functionality.

They are polyurethane with oil impregnated center bushing and are pretty darn smooth, you will have to re-use your mount plate with this kit, working on a complete solution with mounting plate, but wanted to get these out there quickly. Producing some 3D printed ones too, still testing them.

Put an etsy store up if anyone is interested: https://www.etsy.com/DMERCINC/listing/926478734/mercedes-w123-polyurethane-throttle?utm_source=Copy&utm_medium=ListingManager&utm_campaign=Share&utm_term=so.lmsm&share_time=1610563584099
