Will a blower motor for a 1992 Pontiac Firebird fitwork in a 1997 Pontiac Grand Prix GTP?

I believe they will interchange,just look at the wire plug and look at the bolt pattern that will tell you for sure. I asked the question, because I am a dolt when it comes to car repair. I don't actually have the part. I asked, because I wanted to buy a new blower motor, but the one on the jcwhitney website was for a 1992 Firebird, rather than my actual model and year (they do not have one for my specific car). I don't want to waste the money and get a part that won't fit. Thanks for the answer, though.
