Unless you have the equipment to balance the inducer and exducer, the odds are thoroughly against the bearing lasting a long time. You'd have done well to at least have had it balanced and assembled by a shop equipped for the job.
SupraStore has had a fair number of complaints with reasonable turnaround of orders... not uncommon for any small shop though. I don't care if anyone's got a gripe with them, but we've got a section for posting about it... I don't want to hear any more about it in threads that are for another purpose... send a PM or something.
