Am in process of putting one in my '68. Got TKO600 from Hurst Driveline Conversions. So far the biggist issue is with the shifter. Had to cut out more of the tunnel than what I expected due to its design, and the shifter height is about 4 inches higher than the Muncie, so the stock boot can't be used. I plan to put in a thin piece of aluminum around the shifter to fill the gap, then shop for a new boot/trim ring.
