I have their 88 front calipers on my car.
Took a while - week or so? - for them to ship. (When I contacted him, he said there had been an illness or death in his family, so I didn't push it.)
They are a fairly small operation and sometimes take a while, but I don't know of anyone who didn't get what they ordered.
Edit - Amazon - and especially Amazon Prime - has spoiled a bunch of us.
