$124 is way too steep for a gear. They were probably trying to sell you the entire VSS. All you need is the gear that goes on it. Know that if you have a pre-90 mustang, (or something like that) you will never get true MPH out of your speedo. Mine is close with 3.73s, and I paid $3.25 for the gear at ford. Find out what tooth you need, and ask them for one. (worst case you'd need to file down the tip a little like i did) Good Luck!
