I have the TKO-600 with mechanical linkage on my 69. Just as Troy has done, I went with the heim joints and aluminum rod for my clutch linkage and it is very smooth compared to stock.

Can you give some information on the heim joint set-up. What is exactly needed and where can you get the parts.

Thanks

Basically, you replace the factory "pin and rod" links at the clutch pedal to pushrod, pushrod to z-bar, and z-bar to clutch fork with turnbuckles and spherical rod ends.

You can buy teflon-lined rod ends and bulk aluminum threaded turnbuckles and yourself and do it or for just a few dollars more you can get it all delivered to you in one box ready to go, with a rather nice looking billet upper/lower pushrods: http://www.speeddirect.com/index.aspx?nodeID=34

I also highly recommend welding gussets onto the Z-bar. I've broken a couple Z-bars myself on the '65 Vette and had to drive home clutchless (fun!) The Z-bar seems to be the weak point especially with a stiffer clutch, the arms on the z-bar just rip right off the crosstube at the welds. Doesn't hurt to buy a HD (thicker) fork, too.

Thanks Troy, thats great information.

Yes,it is. Thanks,Troy. I think I'm going to order a kit for my car.
