Default Shift rod bracket bushing replacement

For the degenerate 5 speed folks, this is the bracket mounted to the torque tube just forward of the shift lever that locates the rear of the front shift rod. I doubt any of that makes sense so here are photos.






I only have a sample size of two, an '83 and '89, but the plastic bushings were totally disintegrated. I think it is fair to say by now they are all destroyed or will be soon.
These were the remnants I found in the foam.


This is what a new "bearing bracket" 928 424 017 05 looks like. (I found these photos on Sharkskin's site).




The whole bracket is available for about $125 but that is a bit much when all is needed is a piece of plastic. The rubber portion is still intact and pliable. I thought I would put this up to the brain trust to see if there were alternatives or if this might be a candidate for 3D printing?

I have heard a few times of people sleeving that with just the right size PVC Piping split in half, IIRC

Cheers,

Dave

Brilliant thinking! This set my gears in motion.

A 1/2" pvc coupling makes an almost perfect replacement. The OD makes for a tight fit in the rubber and I filed down a ridge in the middle of the coupling where two pvc pipes would meet. The shift rod has a little play inside so I will take another coupling and only file it a little bit so it is perfect. I am thinking I can cut a small groove to secure a zip tie on each side to keep it in place but it is not going to move as is.

My early car does not have this bearing bracket assembly. Not sure when it was added.

It looks like prior to 1981 there was some sort of bearing attached to the body.


This is from the 1981 Service Info manual.

Brilliant work and thank you for the pics. The rubber portion was present on my bushing mount, but I didn't realize that I was missing this plastic bushing. I used 3/4" PVC pipe (the higher quality, thicker style vs. the cheaper 3/4" PVC that has thinner tubing). It's a perfect fit.

i am also thinking of a replacement for this sleeve.
Unfortunately, tube dimensions in inches are unknown in Europe.
Can someone please tell me the exact outer diameter of that shift rod ?
I have from someone the information that it is 20.3 to 20.4mm , is this true ?
Thanks in advance

The metal rod is 20.4 mm, and flares a little to 20.5 near where the flat for counterholding is. The ID of the rubber support in the shifter bearing bracket is 23.5 mm. So you need a 1.5 mm thick plastic ring with an ID of 20.5 mm, or 13/16" ID x 59/64" OD if you're sourcing stuff at Home Depot.
