speedometer guages

does anybody know if you can swap out the typhoon speedo cluster with a 92 s10 blazer. i am quite sure it would fit as far as size goes but i remember reading somewere that there would be a problem swaping mine the 92 blazer with a digital one...basically i am looking to upgrade my speedo cluster cause i would like to know how fast i am going after 85. sounds pretty crazy, but do a lot of highway driving and find my self going those speeds with the flow of traffic but don't know exactly how fast i am going. prefer the typhoon gauge

you'll have to rewire your harness, as well your turbo gauge won't work..
