I am currently swapping in a 98 t56 from an ls1 to my 89 s-10/4.3. does anyboy know someone who has done this swap before without buying weir hot rod's kit. Im on a budget! I know a spacer will be needed and the bellhousing bolt pattern is the same with one hole missin, but i cant decide how thick to make the spacer. Is the spacer all i need to swap it with factory ls1 clutch and throwout bearing?
