I highly doubt you're going to get any knowledge of rod bearing failure history from a sales associate. They know the catalog but not these sorts of "urban legend" issues out there. There's still a question as to whether the issue is really truly an issue.
That said, AA created these bearings for a reason. Because they experienced the problems first hand and were not willing to take the risk again. The rod bearing you appear to need is the STD size 930-103-147-15-M987, which is a bearing that fits all 3.2, 3.3, 3.6 rods thru 993 engines. If you're not convinced, call them up instead of talking to Pelican. I'm sure they'd be happy to talk to you.
