Brass/Bronze Shifter Bushings
Any interest from the group in brass/bronze shifter bushings?
I made up a few sets...
I made the firewall bushing, mid point, and cup bushing.
These are machined to a much finer tolerance than the plastic one and will reduce even more slop...
I will put them in tommorow and give it a try...

If they work out well I might be interested, but im curious, how do you press-fit in the brass bushings, I know with the plastic ones I have done so far, they have taken some coaxing to squeeze them into their spot. thx for the info in advance!

Rich, I too might be interested. Keep us posted on how they work.

If they work I would also be interested. Like Ryan72, I also wonder about the fit, especially the firewall bushing. Installing that one was tough if I recall correctly. I have the rear bronze bushing offered by Pelican. It does not a snap-in like the plastic bushing, but is pressed-in and retained with a c-clip. I got it a couple of weeks ago, along with their sport tranny mounts, but haven't installed it yet.

I made my own rear bushing a couple of years ago, before I heard about one for sale. I think it is essentially the same as the PP unit and so far it's great. I still haven't figured a good way to install a firewall bushing made of bronze and the plastic cup doesn't seem to be a problem usually. I'll be interested to see what you came up with.

OK,
I installed the Firewall Bushings. Basically I made it with a larger flange and used rivets to secure it. The replacement plastic bushing as way way to large...
This one in nice and snug, but loose enough to allow for smooth movement.
This one is a leverage point that had to much flex for precise shifting, and there is no need for lateral movement here, only rotation and sliding in and out..

The cup bushing:
I made that one longer (taller) than the original. This way instead of the cup sliding in and out of the joint, now the ball slides in and out of the cup.
This gave me a way to get much better tolerance at this critical joint. The replacement plastic part was far to loose and at this point on the shifter the slightest play is amplified when it gets to the shifter.

The mid-point bushing going through the shifter housing is similar to the one that can be had at pelicanparts, or GPR. Again decreased the play.
I am trying to find a web site to post the pics at...will get back to you all tonight.

I may be interested in a set, let me know how they work. What about the bushings in the joint that connects the two shifter links?

Does anyone want me to make a run of these?
I would need to understand the number of sets to make to ensure that they are a reasonable cost. The first ones took a long time, many different test...
Finally a good set is ready and installed.

Yes! I am very interested, but lets first get to the important part, how much slop was cleaned up by the installation of these bushings?

also, something that I dont beleive has been touched on, I have a tail shifter tranny, which uses a different linkage configuration then side shift. Despite side-shifters having a better reputation for less slop, I think they might also be on the lookout for imporvement. Your description sounds like a tail-shift tranny to me, what version of the 901 are all you folks here using?

This solution is actually for a side shifter.
I have replaced my tail shifter with this solution.

If there is enough interest I would be willing to develop a set of bushings for the tail shifter as well.

OK,
Price
If I do 25 pieces of each here we go.

The firewall bushing $32.00
The rear cup bushing $24.00
the mid bushing you can get from pelicanparts or GPR.

OK, sign me up! Any way to better the shifting bushings is a steal at any price! I already have the mid bronze bushing and that helps alot.

I?ll take a set, the perfect time to replace the bushings with the car torn apart.
