Nice......The TKO is a 6 spd as well, isn't it? How tall are your rear tires? Do you even get into 5th with the 3.73 rear? I've got 4.56's and 29" tall rears and am doing over 80 mph at 2500 rpm. I probably could have even gone 4.88's but would have turned first into a granny gear. Right now its still useable around town and I can use fifth (somewhat) around 55 mph on backroads.
