Aftermarket shift **** problem
So I finally got sick of the stock square shift **** and bought a new one. I recieved a half leather/ half polished **** w/ a small Z06 logo on it. Nice looking piece, however it was a stupid universal one and used a 7 bushing system to ensure a perfect fit (which is just 7 different threaded plastic pieces with different size holes in the middle). What you do is just find the one that is close to the size of your stock shaft and screw it into the **** then onto the shaft. So basically the thread on the shaft taps the plastic, hold the **** on. Well this sucks everytime I start driving hard it spins. I have emailed the company that I bought it from but they will not respond. Has anyone had this happen? How can I fix it?

I have a similar style shift **** that came with the same array of plastic bushings. When I tried to install with just the bushings, I could never get it tight enough to keep from spinning when I made hard shifts. I unscrewed it and wrapped a few layers of Teflon tape around the threads of the shifter shaft. Then I threaded the **** back on, and after it felt tight I used both hands to twist it another revolution into the correct alignment. It's stayed tight now for several road course events and four 1/4 mile runs on Sat night.

If it were me, I would machine a bushing out of brass with the correct thread size for the inside and outside threads and install it with lock tight. But that just me!
