97snakedriver: I have researched high and low and could not find a 7 tooth for the GT. For some reason they decided to make the 7tooth different for the cobra than for the GT.

We ordered one for the cobra and the splines on the inside of the gear are different from the GT. All straight from Fordmotorsports. You Cobra guys got it good. Unless you know another type. Oh well, that was done when the trans was apart this summer and I'm not about to go thru that again. Thanks for the info. I should have clarified GT T-45 in the previous response. I had forgotten till you mentioned it that the Cobra and GT trans are a bit different.
