1991 Avant Wagon w 3B engine

I have a ‘91’ Avant wagon 20v w 3B. The engine was completely rebuilt in 2011, including a block I got from 2Bennett Audimotive in Davis, California. The rebuild records can be found with Karmakanix in Berkeley, California. The engine has, roughly, fifteen thousand miles as it was only driven around town as a work wagon. It is now impossible to find one little bushing for the shifter linkage so I’ve decided to sell. 037 motorsports sells their own version of that bushing but the last one I had installed lasted ONE day! I believe the 3B
engine fits a few other models so thought I’d check in to find the best place to post
what I have?

Any suggestions on Audi Clubs would be much appreciated.

Thanks in advance
