seville 21cc

First post here! I'm looking at buying a 1988 Seville CC. It has a 4.3 engine. Currently the heat exchanger is missing. The owner says it failed. I have a picture of the engine, and have been searching online for a replacement, but cannot seem to find anything that appears would match up to...

Any help, even suggestions as to where I might be able to purchase one would be greatly appreciated. Used or new, as long as it is in good working condition. Thanks in advance.

I'm looking for a 1988 Seville cc cockpit cover. I'm also trying to find an original engine cover. I know the original was padded and upholstered. Mine is a wooden box, and I'd like to replace it. thanks!
