Just an FYI: This post reminded me that I needed a set of these, so I swung down to the local dealer. They had the new round ones in-stock, $7.95 retail, got them for $5 each... Picked up enough to do the rear doors and have a couple spares on hand. Even if it's not the best deal ever, it's only about twice as much as the cheap ones are and will work better for longer. Plan to install this week.
