Jack and DOES 200, thanks for your responses. I do have a top cover, so need to look at some of the other things you've mentioned. I friend of mine recommended Griffin aluminum radiators, but some of the sites I've found that list Griffins don't include an offering for Pantera. I've e-mailed a couple of them, so hopefully they'll respond -- either with some info relative to availability of a unit for the Pantera, or with some alternatives.
