DUDE! That is way to cool!!! That thing is CHERRY! I woulda jumped on that deal like stink on sh......er...ah....caca!
I used to have a '55 Wlly's P/U that was restored. I literally started my business out of it. I sold it when I moved on to bigger and better big trucks for the work. I wish I would have just parked it to play with later because those are hard to find in good shape too.
Just FYI, there is a place out here in Hayward, California called Archer Brothers Jeep that had every stinkin' part you could ever imagine for ANY Jeep vehicle. I spent some good dollars there! I'll check to see if they're online or still around. They were a wealth of knowledge too.
EDIT: Yep, looks like they're still around. Just do a search for "Archer Brothers Jeep" and they'll be right there on top. Lots of other resources too. Have fun with that thing!
