If that is the bushing that is in the cast housing that fits into the transmission, there are a couple of fixes.

First is the easiest and cheapest and that is to get some very small (smallest you can find) nylon wire zip ties. Pull off the cover and thread several through the hole between the shift rod and bushing. Tighten them and snip off the excess. They do not pick up dirt or goop and last pretty well.

Second is to get or make a bronze bushing for the rod to pass through. They cost more, wear out the shift rod and can cause galling/seizing in that area.

I used the first for 12 years or so on our race car!
