I use a cable on the Cobalt, no paddle though. Lever is always in the same spot no matter what gear, there’s just a small lever on the shift shaft, no need for the bracing that’s used on the J arm. Much smaller movements needed for shifts…
The cables I have built have teflon lining also, smooth as silk…..
This is what I have handy for the shifter, the column end of it. I built a one off for the lower mount to simplify it, I don’t have a production version yet..
I guess it wouldn’t be too difficult, but I steer with my left hand, and it doesn’t bother me to shift with the right. Look at my video, you can barely see my hand move on the shifter….
Dean, I can see it fine, but here’s a link to the webpage
