Not sure if there'* anywhere to post interchange on different cars. But, certain years GM used the same EXACT headlight on Bonnie'* and Lumina APV'*.

Yup same on the Pontiac and Olds vans too

but NOT the corner lamps...

correct, too bad

Yup yup.

Pontiac, yes, on the second-generation Trans Sport. (I own a '96.) But Oldsmobile retained the original shovel-nose design on their Silhouette and never adopted the second-generation design with the Bonneville headlamps, so the Olds Silhouette won't do you much good, unfortunately.

When we unload our Trans Sport, probably in the next 3 months or so, I'm going to be swapping the driver'* side headlamp with that of my Bonne so I can finally get rid of the lens with the stone-chip bullseye on it...
