Newbie needing a little help

[hootlube]

Hi guys and gals,
I joined because I need help with my Eaton 052. I'll try to make a long story short...
Resurrected this truck (71 C20) from the pasture. Had to put a motor in it, the list goes on, right? So last year, I decided before hauling firewood it needed brakes. Seemed so simple... so, I started taking the rear drums off.
Days later, many tools and parts purchased, I got it back together. Headed to the woods, burned the outer bearings on the passenger side.
I've since been looking at many of your posts, and they've been incredibly informative. Thank you! I think I've learned some of the things I did wrong... I guess we'll find out when it goes back together. The housing is at the machine shop, should come back in a couple of days. I've rounded up all parts except:

(I think I did that right) there's a retainer clip, and two bearing nuts and a lockwasher that got trashed. Does anyone know where I could find these? Any help TRULY appreciated. Thanks, hootlube@yahoo.com
