23 tooth speedo girl will fix your speedo, thats what I have with no problems. It is simple to install, but if they are installing your gears just have them slip the thing in your trans because I don't know about you but its winter time here and I hte even having to put gas in my car outside!!! hehe...see ya
You will need to go with the speedcal if you want it close to accurate. I ran the 23 tooth speedo gear in my 96 with 4.30s and it was reading 5mph too fast by 45mph, I don't know how more inaccurate it got at the higher speeds. Also the speedo gear will get worn down very quickly in a matter of just months. I went with the speedcal and it is dead on accurate
