Thanks guys. That’s what I was looking for. And David, I thought your post on the tires was very relevant for a car board restoration forum. I enjoy this board for the Q and A, not the crap that goes on in the unmoderated forum. Unfortunately, that attitude bleeds over to the rest of the forums. I see mistakes made all the times by uncaring restoration shops. I’m dealing with a bolt that was placed where a stud should have been. The longer bolt punched a hole in the cowl of the car and it leaks into the car when it rains! How stupid. It’s in a hard place to fix, as well. So anytime I can help people not make an informed decision is better for all.

Anyway, back to the subject. I can see the washer being a good thing on a pie pan equipped air cleaner. It saves the paint on the aluminum pan.
