Tommy,
I've got a full set of DID "A" rims, but the shoulders on them are much taller than that Akront and they'd look funny together. What I need is the first rim on Buchanan's DID page:

RDWM12140 the WM1 1.60x21 aluminum 40-spoke, dimpled, non-shouldered rim. I was hoping to find either a used rim that was similar, or a new one for less than $150, but if need be I'll go with theirs.

OR, if I could find a 4.25" or 5.50" wide shouldered rim that looked like the 19" DID "A" rim I've got for the front I'd run that. But I can't find a reasonably priced wide shouldered alloy rear rim either...
