Like Freak says, if you make a few modifications you will not need an adapter. The WC t-5 was used in some 93-95 S-10s. I have 2 of them. The 89 up & some 88 had the electronic speedo drive. You cannot use the original speedo with them without a special converter that is expensive. The NWC T-5 is just about as good. I have used them behind 350 v-8s with no problems.
