Excellent work. Agreed having to pull the tube and weld it seems a drawback. Agreed also with others that you might look for a solution that allows installation with the tube in-place. I agree that a good clamp should be a fine option.

Congratulations, Sam. I have submitted your creation to the Society for evaluation and the committee has agreed to issue your certification. Based on the merits of this creation you are now FBA Certified. Way to go.

That's really nice looking! Should work great for any "track" application. Street "use" might be interesting.
I'm going to guess that Porsche mounted the shifter the way they did to help keep vibration/noise from the torque tube away from the gearshift lever. I've found that the majority of the time, there is always a good reason why the engineers did things a certain way....those German engineers aren't stupid!
The torque tube is bolted solidly to the engine and the transmission. It's going to shake as much as the engine does...multiplied by the length of the lever. I also can't imagine that hollow tube being very quiet.

True to most who are FBA Certified, Sam has discretely asked me by PM about the certification he has recently received. I told him I would post the response here.
I am a founding member of the Society of Fabricating Bad Asses. The society is devoted to recognition of outstanding achievment in the area of creation and fabrication of just about anything. Sam has demonstrated that he can concieve of and then create from, something else the item he is demonstrating in this thread. His creation needs not be proven to be better thatn something else or even as good; but it must be shown to be individually created and fabricated from something else (other materials), and it must show a significant level of workmanship and skill that is greater than just assemblage from other things, although there is a limited category of certification reserved for mere assemblage, but only in very unique circumstances.
Certification by this Society of Fabricating Bad Asses, means that Sam in now a certified Fabricating Bad ***. Hence FBA Certified.
Again, Congratulations, Sam!

I paid $400 for short shifter parts (short shifter and selector rod) for my BMW and it is pathetic next to the normal short shifter for the 928. The brand is "UUC" which is one of the top names in that stuff. The Lizard shifter is in another ballpark again with the short direct movement.
