[Agent_4573]

If the GT you got the cluster out of had 3.73's and you have 3.73's you should be able just drop the speedo in and it will be acurate. If the GT had the stock 2.73's or 3.08's and you have 3.73's you will need the different gear. I did a search and found this site, http://www.steeda.com/store/-catalog/speedometer.htm It should be simple enough to find what your looking for there. I believe all the colors are the same no matter who makes the gear, so before you put the speedo in, take a look and see if you have the right gear to match your rear gears. Take into account also this is for the stock 15 tires. If you put on 16's or 17's you will probably have to account for that also. Just do a search on google.com or somewhere like that for speedometer gear calculators and you'll get a shitload of sites that you can use.
