Dealer Part, Or Just Bad Luck?

[IndiEP]

Is the DRIVERS side tranny axle seal a dealer part?

I got the passenger side from NAPA and it fit no problem, the stock drivers side had a copper casing and an outer lip. The replacement part is to big, even the stock passenger seal doesn't fit in the drivers side. Tripple checked the parts #s w/NAPA and supposedly their the same. Went to Bumper to bumper and they pull out the exact same part NAPA sells. Its also Saturday night, hence I have not called the dealership.

And while I'm at it, is the transfer case out put seal a dealer part too?

Thanks guys.
