930 Trans shifting issues

[5.7 GT1]

I purchased my 1988 930 last year. When I purchased the car I noticed the shifter was really sloppy. I replaced two bushings at the shifter in front and the coupler bushings with delron ones from our host. That helped a little. The shifter travel is extremely far from 1st to 2nd and 3rd to 4th. It seemed to be getting progressively worse and some times would pop out of gear. The shift into 3rd never felt really positive. I spent a lot of time trying to adjust the coupler into the sweet spot that would be just right giving enough through from 1st/3rd to 2nd/4th. I could never quite hit the sweet spot.

I decided to replace the shifter with a wevo unit, hoping that it maybe the stock shifter was not performing correctly. That didn't make a difference. In fact the wevo had less travel than the stock unit causing it to pop out of gear easier than it did with the stock unit.

Hayden at Wind rush/ Wevo was very helpful with his product support. As we went through the process of elimination:

All new shifter bushings check
new coupler bushings check
correct installation of the wevo unit check
correct adjustment of the coupler check

He mentioned the fulcrum fork could have come loose and that could be the cause of my shifting issue.

Can anyone on this forum offer ideas of what the issue could be from a similar experience?
The only other issue I can imagine is a loose sift fork??

Anyone that could chime in and offer advice on diagnosing the issue would be much appreciated!

I'm stumped.
