Aaaannnndddd 8 years later I found something that works, at least for the 87-88 cars. It's made by 3m, Silver Polyester Metalized Film Tape 1/2" Width.

Grainger sells it. A 5 yard roll (15 feet) is enough to do the rubber side moldings between the wheels. It has an acrylic backing (like body side molding tape) and, if applied to a clean, grease free surface, sticks like crazy. It only needs to be trimmed at the ends as it is the perfect width to cover the chrome strip in the moldings .
It's holding up great. Still looks like when I applied it. A caveat: my car lives in a garage (sometimes also under a cover) when not in use, is washed with water twice a year (the rest of the time is quick detailer or waterless wash), and lives a pretty pampered life. If you car doesn't it might not last as long. If/when the 3M tape goes bad I'd get a vinyl graphics shop to cut me a 1/2" diameter roll of chrome automotive vinyl and use that.

Maybe I should just go with this instead? Think it would hold up better?

Edit. I pulled the trigger on the above link product, well see how it goes.
