Ok I jacked up the car this weekend, and did the tape thing. The Drive shaft turned about 3 and just under a 1/4 turns so I am thinking stock gears. So I went back out on the hwy cruised at 80 sure enough about 2300 RPM, then I drop into 4th 2700 give or take. So maybe I was in 4th that time. Go figuer. The car is still pretty quick of the line. Not sure if I should even change the gears out. Thanks for all the help and Info. ACR the car looks good.
