Can anyone tell me the part number on the Crower website for the bushings I would need to make the 21 mm wrist pin LS rods work with 19 mm D/Vitara pistons? I've been looking around on there and not having too much luck. Do they even make such a thing anymore?

 

Yes they make them. It's just silicon bronze thats used in most if not all aftermarket rods. Just have your machine shop call crower and order them to the size needed.
