Hello,
As for spacers I have a set made by Sky Mfg. They are great(Diggers are lower priced and do the same thing) He didn't make them when I got mine,Or I would have Diggers...As for the body lift I got a Sky Mfg. I think it's the best set up,Calmini's kit is just square tubing,If you want that just make your own,Sky has a sleeve nut that goes in the mount,Also you don't have to mess with a lot of junk,And it looks like a real bodylift and still has the rubber mounts...
Later Tom K.
