Hey everyone I had a question about mustang gearboxes. When I took mine out I noticed it was blue and had yellow letters on it. I figured it was a previous owner and I painted it gray like most other tranny's. However I saw another 4-spd for sale and it was also blue with yellow markings. What gives? If it's owners doing this then why the yellow markings that look like part numbers? Any info is much appreciated.
