No diff Joe. Either will work. What year is your engine?

Paul,

The guy that  purchased it from  said it was an 89.  If I place the rotor
from the 88 next to the 89 rotor the " bathtub" looks the same.  I will have
to find a 2nd gen rotor housing.

Hi Paul,

Well it looks like I have one good rotor housing.  I
think it takes someone who is new to rotaries to look at a lot
of hardware.  My 88 housings were bad on the eges where grooves
were deep these 89 housings looked great until I got to the
front housing.  It definitly ate an apex seal.  After I lifted
the intermeadiate housing off I found a loose apex seal.  This
is what caused the damage.  Is there a difference between a
front rotor housing and a rear rotor housing?  Pics were too
out of focus.  Will post when I figure this camera out.  Thanks

If you buy a used one make sure it has not shrunk.
Use a micrometer to measure the width all the way around.

Here is a pic.  It might have been a two piece seal.  The short portion was
probably expelled.  There is a groove lower left of the exhaust port,  There
are also some marks toward  the right edge where the seal made impressions.

That is not that bad. Send more pictures.
