I see there is a 1989 Camaro convertible going on the 'Bay, however, it does not have a 350 engine it, BUT did win more then a few awards and is ending today. Selling at just over $6000 when I saw it today

Seems like a real deal for the auction bidder

There is also a top with frame and weatherstripping, but the reserve is quite high and out of my range.
Again this post is a bit OT, but there is a 1989 Camaro droptop postcard also on eBay. I bought from the seller before so they're good.
