Hey guys I'm getting ready to install my Ford Racing speedo recal I got from American Muscle, and the instructions it came with are decent enough since I do have some automotive knowledge, but I was just wonderign if anyone has installed one of these and come across any issues I should look out for? I plan on doing the underhood install, so where is the best place for the ground? Someone mentioned running it all the way to the battery negative terminal?

One final question, I installed 4:10 gears in my mustang 6 years ago, and I cannot remember what my stock gears were. Is there anyway to tell if they were 2:73 or 3:27? I've looked online and it seems to be a 50/50 split of both.

Thanks!

You should be able to either crawl underneath the car and look at the tag or find what the rear axle code is on the door sticker of your car..
