Did this modification/replacement of the dogbone link... In the dark.. Yeah, getting the locking clips installed was a nightmare, but once I got them installed and hopped in the car and felt the difference it made I was very surprised and pleased. Well worth the $10 in parts and 15-20 minutes of my time it took to do this!New "dogbone" shift link, alongside the nasty, loose old one:
To give credit where it's due: needed parts info was found from this page:
Get your parts from McMaster-Carr (plus two M8x1.25 nuts from, well, wherever.)
For searchability: you'll need two 9416K79 rod ends (10mm ball socket, w/ M8 inside threads), and one 93275A035 (M8x1.25 threaded rod, 130mm (ish.) Shorten threaded rod to 110mm. Assemble, and set to the same length (center-to-center) as old part.
Install. (Have fun getting the locking clips installed!) Enjoy all-metal dogbone link, in its slop-free glory.
Cost? About $10.
