Randy has all the rear end parts cleaned up and ready to be painted, but I haven't done much to hold up my end of the deal.  Between doing taxes all week, and having to mow the lawn tonight (the one thing I dislike about spring and summer), I haven't been able to spend much time on the B.  But I did find a source for the clips that hold the leafs together on the rear springs.  They aren't original, but I think they'll look ok after painting.  Tonight I disassembled one of the springs and cleaned the center bolt and the small top leaf.  I also put a coat of primer on the backing plates and a couple of brackets.
 

This shows the center bolt in the leaf spring with one of the nuts removed.  It uses a double nut to lock down the leafs.

It's hard to see, but this shows the orientation of the leafs and the clips.  The hole in the middle of the leafs is offset toward one end.  The end that is farthest from the hole goes toward the end with the smaller bushing hole in the longest leaf, and the rubber pads for the clips go toward the bottom of the spring.

Another shot of the spring assembly.  The teflon pads between the leafs were pretty well worn out.  My brother-in-law said there is a place in Mt. Vernon that sells it, so I'll have to look them up.
