1989 Wellcraft blower side vent outlet cover.?

[Steve]

I want to replace the side blower vent outlet cover on the left side of the boat ( cracked). It's a black plastic peice on the outside of the boat that covers the vent outlet of the blower. Problem is being a 1989 (23 years old) I can't seem to find this part. If anyone knows a good place to find one your help would be greatly appreciated! Thanks.
btw the boat is a 1989 wellcraft 186 eclipse XL.

Rather than spend hours of time trying to find an obsolete part, why not pick out a pair that are close in size and style from any marine supplier, and change both sides?
