speedo gear

i was looking at my invoice and the part number for the gear says 17271A. i looked it up on 50resto and it says that was the PN for the pink. i knew something was wrong. i picked my car up yesterday and while drivng around on the highway today i was thinking to myself no way are all these cars doing 90. i was trying to keep up with them. same with driving on city streets. im doing 40 and it feels like 30, everyone passing me. i will call the guy who installed them tomorrow, see what he put in there.
