My fairly-new-to-me -6 conversion has a Patrick Motorsport linkage. I would politely offer that it's not their finest piece of work. One of its shortcomings is that the firewall bearing is a spherical bearing in an aluminum holder. Thus there's metal to metal contact and after what I think are less than 1800 miles there is noticeable wear on the shift rod/tube.
I can see the logic behind using a spherical bearing; it allows for any slight misalignment of the rod from horizontal. But the metal to metal contact is crazy. Any thoughts on an alternative solution? Attached thumbnail(s) ![]() ![]() |

That’s a great find @Steve - looks identical. The shift rod is indeed 3/4” in diameter and the bearing’s OD is 1 7/16”. And note it’s meant for a steering shaft that merely rotates, not a shift rod that slides in and out.
@ChrisFoley , what are the dimensions of your bearing? I have found products like https://www.igus.co.uk/product/391?artNr=EGLM-20 and https://www.igus.co.uk/product/381?artNr=EFOM-20 but they’re all either for 17mm or 20mm shafts. |

I think they sell both shift rods. One for the stock bushing and one for the metal bearing. I am also curious if you could just use a stock shift rod and make it work with the CFR bushing and PMS shift rod to your side shifter? |
