Home-built short shift kit
I couldn't swallow $200-300 for a really good kit so I made my own. Obviously I copied someone else's design(cough, cough), but this cost me a total of $59 including the new 1/2" end mill, 5/8" drill bit and shipping. Yes it took a few hours...but it was fun! This is just the mock-up. I'll make it pretty after I determine that it works. It has just two settings, stock and roughly 30% shorter.

The three heim joints, the end mill and the drill bit came from McMaster-Carr. Although they don't use the term "heim joint". They call them "rod ends" in case you want to look them up.
Thanks for the compliments guys!

Prettybird, that's funny right there! I don't care who you are.....
This is on a 1984 944. Oh, it "works", no doubt. However, I haven't put the car back together yet. I will know before the new year if it works well enough to be called a success.
Mike C - If you want the part numbers for those heim joints, I can search them out.

Looks good. I have the "commercial" version on a couple of cars. Weak point seems to be the bolt that clamps the shifter to the shift rod from up front. Always coming loose, and then tranny connection gets wacky. Have used loctite with some success. Safety wire probably best/better, but not easy for everyone. A good secure connection would be a very desirable feature.

I'm not sure I would use anything but a PTFE lined / sealed joint for this. Granted this is not a suspension component that would be a dangerous situation if it failed, still a major PIA and in an area that will get dirty.

I agree on both points; securing the bolt and the telfon sealed heim joints. This is just a test setup so I bought the inexpensive joints. I will probably safety wire and loctite the bolt just so I don't have to think about it, and on future units I'll include the good joints. Also I could include a set-screw to hold that bolt. Thanks for the experienced input! Hell, I might do that now since it's still out of the car until tomorrow.
About selling these. That's a slippery slope. This is copied from pictures of a race company's unit. I'll give credit where credit is due. Let me get a couple thousand road miles and a couple track events on this one before I pat myself on the back. After that I would not be opposed to making a few up for the Rennlisters!

When you get a chance I would like to keep those heim joint part numbers for future reference. As for the sealed joint, I've had my Autothority kit installed for (at least 13 years) and 150K+ miles without a sealed joint and it's still pretty tight.
