Different types of Sunfish coamings?

I've got a cockpit coaming that's supposed to be for a Sunfish, however the shape is a bit different from the one we have on our 1978 Sunfish. This one doesn't have quite as sharp of an angle on the forward bend and the two sides are a bit more curved. I can post a picture later but don't have one now.

Did Sunfish ever make a differently shaped coaming?
