I got a car!
 

Yesterday I picked up my new car. Its a red 1990 GT. Its got a Hurst Competition shifter, Flowmaster H-pipe, a Flowmaster exhaust that dumps before the axle, and 3.73 gears. I really like the car so far and I'm getting the hang of shifting it too.

Also where can I get the gears to recalibrate the speedo since it wasn't done when the 3.73's were installed. Thanks.

Congrats! When you get a chance post some pictures for all to see. You should simply be able to go to your local ford dealer and tell them you've got 3.73s installed, they'll sell you the right gear that goes in tranny. Simply pop the old one out and in with the new.

Congrats on the new car!!

As was stated before, your local Ford dealer will have the correct spedometer gear.
