Is there a way to tell, different year rotors apart from each other?

The reason I ask is there is

a guy who says he has a set of 89-91 rotors for sale.  But I don't

know

how I would tell them

apart.  Any help here is appreciated.  Tom Webber

Tom,
They weight less than the previous years models by a bit. I had an
engine of unknown year make and took them out and to a supermarket in a
plastic box and had them weighed. Mazdatrix, I believe has the specs for
the different years that correspond to the weight on their website.
http://www.mazdatrix.com/faq/rotorwgt.htm    9.54 lbs for a 91 nt is
listed. Mine turned out to be a 91 motor. The manuals may also have that
spec.
