I pulled these upper and lowers off of my truck about 3 weeks after I bought it (new) when I installed a DJM lowering kit - as you probably know, Toyota does sell JUST the ball joint, so I had to take them out of the stock ones.
The arms are complete and in PERFECT condition, aside from not having the ball joints - I honestly don't know how to price these with all things considered, so I'll just say $400 for the set, $200 per side.
the link below is just a site I found that deals with OE equipment, maybe it'll be of some use.
I also have the stock single CD head unit/dash piece, lookin at $75 for that, and if you want the u-bolts, those are free! haha, just pay for shipping...oh yeah, and the mud flaps...free too!
