For those interested in tightening up the shifts, but can't quite cut loose of the $$ for a MGW shifter (or any other brand for that matter), a cost effective alternative is to get the Saleen adapter that's available for only $45 directly from Saleen
This is what I had installed for almost a year before switching over to the MGW.
The inlcuded Saleen instructions were accurate. However, the small B&W pics (hard to see) and 4 pages of instructions made it more confusing than it really was.
When you see the pics below, it'll make sensewhere the shift block goes (and it's orientation) and how everything attaches.
Here's some tips I gathered(not in the supplied instructions) that helped me along;
Lube both plastic bushings (outer) before inserting them into the Saleen block.
Lube the Saleen silver bushing (outer) before inserting it into the shifter barrel.
Lube the shank of the shift linkage studbefore inserting it through the plastic bushings (in the Saleen block).
Loctite the OEM nut that goes on the shift linkage stud pin. Use caution when tightening this nut, DO NOT OVER TORQUE IT! I only brought the nut down until it made contact with the plastic bushing, then gave it an additional 1/8 turn. If you tighten this nut too much, it'll make shifting (into the gates) very difficult.
Let the Loctite dry before any extended shifting drive.
Here'sa short video showing the shortened throw of the shifter.
