Non-Adjustable Front Shifter Link Replacement
Earlier this year, I made a run of adjustable pivot clamps to replace the front shifter link. These were heavy-duty, fully customizable (and expensive) parts to do the "simple" task of eliminating the front link, guide bushing, and pivot cup.
I had several people inquire if I would make a simpler version, something easier to install and without all the adjustments.
So, the P9-MS03 was born. I am machining a test batch now.
These will use the same Igus Z-series bushings I used in the adjustable short shift levers, so the action will be smooth and have some vibration absorption from the proprietary material.
Here are some pictures and a 3D web model:

This configuration uses the same arm as the fully adjustable clamp, but the attachment method is a 19mm wide stainless hose clamp and waterjet cut bracket.
A similar shifter system was developed and by Mike Simard and run on his track car, so I will not take any credit for originality of the design, but the execution is a bit different with this version.

I'm guessing this design can be installed with the torque tube in place? No mods of the foam?

Now that I think about it, I couldn't (when I fitted a Lizard shifter on my '85) - I ended up strapping it to the TT.
Which makes me think the TT has to come out to install this version, too, because of the bracket which holds the shift link.

It may be possible to install from under the car without dropping the TT, but its not going to be easy. Tiny hands and extreme patience could prevail.
I would plan on dropping the TT to install. The foam still needs to be slightly modified, but much less-so for this version.
This also uses the Igus Z bushings, so it will transmit less vibration that ball-bearing from the adjustable design.
Its nice to have options, and this makes sense for most stock replacement applications.

the holes for the studs on top of the TT are elongated, so I assume there is some sort of fore and aft adjustment, or is this strictly for installation purposes?
if those are for front to rear adjustment, is there a guide in the instructions as to the exact location for the clamp? does moving the clamp forward or rearward affect the geometry of the throw?
