Kind of an odd and scarce item. I guess there are a couple of styles on ebay, but I haven't seen this original style.
This kind has the arms that come all the way up and mount to the floor pan of the trunk, rather than the bottom of the spare-tire well. The other end mounts to the underside of the rear bumper.
Chrome has surface rust, but totally usable.
$35 plus shipping.
I'll post pics shortly.
He was thinking about a concert when he wrote this ad, ha.
