Can't update the old thread, so here's a new one.

940 wagon -- the link between the shift lever which goes through the shift assembly and the shift rod which goes to the transmission had come apart.
The two are connected with a pin going through a bushing, and an E-clip. The other end of the pin was still fastened to the transmission rod.

Bought white plastic bushing #666143 (FCPGroton is one supplier), which when viewed from the side looks like a capital I. I trimmed one end off to make it easier to push into place, sprayed some silicone on the bushing, placed the pin back through it, and attached the E-clip, adding a thin washer between the clip and the bushing.

Hope this helps somebody.
