The bushings in the front coupler. One was totally disintegrated and the other missing a chunk. $40 fix (thanks @dr914 ), including two new cone screws. Took me about an hour. Getting that pin out is a bit of a bitch! Impressive difference in shifting!

Thanks again, everybody!

And what are these "cone screws" you guys are referencing? Thanks guys!


See the Allen-head fastener in your second pic? That is the cone screw. Or rather, one of them. The other screws in through the shift rod head that goes on the rear end of the rear shift rod, hiding up above the plastic boot on the side of the transmission.

Yes, I figured that out. Thanks Dave. Really appreciate everyone's help here! I ordered a set of brass bushings and new screws yesterday. Hopefully that fixes the problem.

Why brass bushing ? never seen the point of them,same effort to fit the stock plastic ones ,admit there is some great aftermarket parts to improve shifting with our cars but IMO these are not one of them.
My system is far from stock and is custom built due to 6cyl motor but I found the Tangerine bulkhead bush was the best improvement from the loose fitting factory stock one,second best was going to oilite metal bushes in the shift console after going to dual bushes and rear shift rod uni-joints x 2.
This setup isn't for everyone but certainly look @ the oilite bush from 914worke for the rear console and the Tangerine bulkhead kit ,both of these remove lost motion from the system which can hardly be described as perfect even when new.
Good luck

P.S. the pic is early development of this conversion,somewhat refined later on.
