Shift coupler bushing source

Shift coupler bushing source
I just tried to replace my shift bushings, but the new ones I got really are no better than the old ones I have. The holes for the pin aren't even round. They are ovals. That doesn't make any sense to me, although my old ones seem a little oval also I guess. Is this somehow the way it's supposed to be? I can't imagine. Does anyone have a source that they used that they were happy with?
Thanks

Plenty of great 928 vendors available. I'm slightly partial to 928sRus where I purchased my shift bushings and they worked great. I'm also a fan of 928 International.
It's been about a year since replacing mine but I don't remember them being oval.

Brand new factory bushings are oval as shown in this parts layout.
Just below the standard oval hole bushing in the pic is a delrin bushing with round hole, that 928'sRus sell as an alternative to the factory parts.
I've got delrin in both my cars and they're much better.

I think there is more than enough slop in the shifter bushings and the forward coupler to absorb vibration in any case. Bronze bushings can sometimes give a bit of a buzz, but delrin as shown don't give vibration issues.
It also perhaps boils down to personal preference and your shifting style. I prefer to shift with a light grip and guide the shifter through, and allow it to 'find' the gear; and tight notchy gearboxes rather than 'stirring a bowl of porridge'.

This is the first I've seen these. Does the rod #3 above just press out and allow you to swap bushings? My shifter has a bit of slop and I was going to start investigating the cause. Can these rear bushings be replaced without dropping the torque tube?

Yes, yes and yes. No need to drop the tube, but might need a bit of contorting involved. Also, the little allen set screw may or may not give you some headaches. There are some really good threats and diy articles on replacing the coupler and bushings and also on the procedure to adjust your shifter when putting it all back together. Search will turn them up!

Harsh. Not to hijack this thread but will the new bushings fix the shifter buzzing I've developed, or is that another problem? Did some searches but there's nothing posted indicating my symptoms (that I could find). My shifter buzzes all the time, even sitting still in neutral, a little push forward or back and it stops. I'm thinking maybe a new short shifter & some bushings while I'm at it? BTW, the front ball cup was changed out a few years back with Carls unit so that's not the problem. Any opinions?
