Oh the joys of shopping online... last week I bought some motor mounts for the MX-5. The parts arrived Monday, part numbers matched and parts were sealed. Great! Except not. The part must have been incorrectly listed for my application, because it is slightly dimensionally different, and all 3 locating 'nubs' that center the mount are in the wrong place. Evidently this also happened to another member on miata.net, with Rockauto, but with a Beck/Arnley part. He sent in some photos and got a return without paying return shipping (my goal). I sent RA some photos using their online return service, and I'm waiting to hear from them.
