Got the TKX and a mid shift for the car a week or so ago, forgot what final gear it is but in 5th and about 2000-2200 rpm will be about 72-75 mph with 3.90 gears in the 9 inch from a 79 lincoln I got blasted and primed in weld thru primer for the car. Hopefully soon the chassis will be done and can go for blasting and powder coating.
