Quite rare now, even though this is not the early type as it has the array of round holes. Could be expensive as $61 with 6 days to go.

My car had one of those when I got it. It had accumulater quite a lot of grease/dirt/crud on it. I took it off when I added a swaybar. Didn't see the advantage of it. Mine had larger holes towards the front of it though.

Did all cars come fitted with these?
