So here's a quicky comparison of the tranny / gear change reasoning.

With the TKO 600 FIVE speed -- the OD is .64 - so using a 3:90 gear - and a 275/60/17 tire (30" diameter) I'd be in 5th gear cruising at 2000 rpms at 71 MPH

If I kept the T56 SIX speed -- that same RPM and rear gear would have me cruising at 80

Rear would need to be a 4:56 to get me to 69 MPH using the T56

In a "normal" car -- with "normal" size tires -- this wouldn't be the case - but the tall rear tires used on "highboys" really creates it's own situation with gearing.

As an example - lets assume the same as above - but substitute a 26" diameter tire

The Five speed/3:90/2000RPM would be 62 MPH
The SIX speed/3:90/2000RPM would be 69.5 MPH

So the SIX speed T56 is great for a PT car etc that doesn't use such tall tires.

And yes -- it will be for sale - it's painted Ferrari Rosso Red --
