Keep in mind this was 10 years ago. MDL was not doing Cougar speck kits at the time. I also ordered the kit from C J Mustangs. It went in fairly well. You can see the few difficulties I had reading the thread.
As a review, I love driving my Cougar a ton with the 5 speed. Only think I wish I had done was use a TKO or TRX rather then the T-5Z.
