With our engine, transaxle, oil system and even exhaust installed in our soon-to-be-V6-powered 1991 Toyota MR2, we’re down to small details and reconnecting previous bits where they need to go.
Unfortunately, since we had a little fire in that very same engine bay, the work isn’t turning out to be as easy as plugging and playing. We’re still finding …
You might want to try brass.
RacerX makes those bushings of you haven't come up with a solution yet.

Seems like Delrin would work well there.
It would be nice know what the bushing was made of originally. Y'all have some clout and maybe a shout out to Toyota from yuz guys might actually get an answer. Original parts from our 90's Toyota rides are disappearing from the factory 'catalog' at an alarming rate. Some other manufacturers (Toyota included) might want to pull a page out of Porsche's and Mercedes' playbook and maintain select parts for older performance vehicles that are still loved and maintained by their keepers AND can be sold for top dollar to said proverbial keepers of the flame. It's not a typical practice for high volume manufacturers, but it seems to generate a bunch of coin for the Stuttgart based folks.

Sorta related, I’m about to drop the 911’s engine for some work. While it’s out, my mechanic said we should replace the bell crank bushings–along with some other “while we’re in there” things. I had several options to order from including, IIRC, factory Porsche.
In reply to tgschmid :
There is a Toyota Heritage program that has made available select items for the 2000GT, and a few Supra bits. I think some AE86 parts may have been done as well. Unfortunately, the parts that have been made available... I'm really not sure who is asking for them. It's starting to become a joke.

There's no such thing as "too light." There's "tires too skinny," "not enough downforce" and "underdamped."
Yeah that's what I ended up using.
Surprise teaser for the next update: we figured out the issue. It was tertiarily related to the linkage, but more related to be being dumb.
I'm currently trying to get my 2GR MR2 shifter sorted out, so I'm following your progress. Mine has an E153 and shifts, but you can't shift quickly and the feel is terrible. I'm doing the adjustable shift cables from MR2 heaven first, along with the shifter fork bushing and shifter base bushings. Hopefully that sorts it out, but if it doesn't this will probably be the next place I look.

I've actually had pretty good luck with sizing brass from spent shells after I've gone shooting.
Could it be geometry rather than material?
If the two parts twist relative to each other through the range of motion, having the center hole rounded rather than cylindrical { )( instead of || } might free up the angular motion without making it sloppy.
