the one that does have a part# is 807988-C.

Right side and left side are identical. Google on the part number and
you will get hundreds of hits. Mercruiser parts have a better finish
than the aftermarket ones. Price isn't a huge factor any more. You
shouldn't have any trouble finding what you need.
