Default Which Shifter lever position? Mid or Rear?

Hi All,
Trying to figure out which is the best shifting position on the TKX trans?
The mid would require a shorter shift lever arm while the rear is more like the original cobra, long arm.

I don't want the car to feel like I'm shifting a school bus and don't care about originality. I'd rather have the smoothest and best possible shifting.

Thanks for any input and opinions.

David

The mid-shift shifter position on a TKO or a TKX gives you a naturally positioned shifter, much like the T-10 shifters in the original 289 cars. You lose the long gangly, forward-bent Galaxy shifter geometry that Shelby turned around and used in the original 427 cars.

For your effort, you get a comfortable shifting, naturally positioned, intuitively located shifter pretty much where you expect it to be. You also get a very small improvement in shift quality because the portion of the internal shift rail system used in shifting from the mid-position location uses fewer internal parts, is shorter, and more rigid.

For the period-correct crowd, notably, it is also not period correct. That said, neither is a TKX five-speed OD trans ...

David is getting a MK III (427 style) car. Superformance supplies the Galaxie type shifter which works fine. You learn very quickly that shifts are "up and down" rather than "back and forth" as in a 289. You can of course use the 289-type shifter and will the use the forward or mid mount.

Thanks Rick
Didn’t realize SF supplied the shift lever

That is if you do not plan on racing the car. I removed mine after my arm restraint (you have to wear them in an open car to keep your arms from flying outside of the car in a rollover) got caught on the reverse lockout and wrapped around the shifter

Plus, the "lockout" bar is cosmetic. The Tremecs do not use it.
