Doc Diff's are $100 with free shipping, bolts and all. They may not be concourse, but it's a good deal for a brand-new niche part. and I'll probably wind up with those.
Still, I'm wary of any non-factory reproduction cast suspension or brake part - at least those designed for use on a factory street car. Doubly so since the repops don't have a country of manufacture listed (not that we do that much better here in the U.S. anymore, given the company). Case in point, the Chinesium from Right Stuff and their cracking spindle snafu.
I'd feel more comfortable with a set of factory units, but I'm not going to pay more for originals to erase a question mark in my mind - especially since this part can be pulled off of any malaise-era Cordoba.
