Never saw a washer under a '69 A12 air cleaner wing nut or a Lynch Road Hemi Road Runner......This is the '69 survivor F8 Hemi Road Runner wing nut at Carlisle 2005. BUT there is a washer under a '69 survivor 383 Super Bee from the same event and also a Lynch Road assembly car. Also on the Hemi RR you can pretty much tell there was never a washer there for a long, long time...................maybe when it showed up at the dealership but not after that.....just an opinion and you know what they say.

(Mike I think those are the rare original air cleaner wing nuts in the Hemi close up if I'm not mistaken and pretty sure that's why I took those photos at Carlisle. Have a photo if the battery hold down wing nut from the same Hemi RR If you like......and I think it has a WASHER under it
