Complete rear brake set up sbp 10 x 1 3/4 drums

It's not like the stuff weighs 300 pounds or something. I'd keep it all together if I were you. It's not really a big deal to ship. I've done it several times. Even though most parts are probably going to be replaced, it's really nice to get all of the pieces assembled, so you have a good starting point. There are a couple of parts that aren't available new, so at the very least make sure you include them. Heck, I'll give you $80 for them, assembled including drums, and pay shipping to get them here.
