I've been told a S10 T5 tranny will bolt up with no mods other than an appropriate clutch disc, but , I've also heard the input shaft is a little long ( 1/8 inch ) and has to be shortened or an adapter used to correct this . Which is correct ? Also , I have a 3.73 rear end and wonder how well this OD tranny ( an '85 - 87 )will work with that ratio in the rearend ? This truck is going to be a " cruiser , not a bruiser " and I want the tranny for not only better fuel mileage , but , also to allow the engine to not have to run so hard on the road at cruising speed .
