"3905569 washer-sealing" on 69 Camaro
 

The 69 Camaro AIM (UPC 4 B3) shows a sealing washer on the rear shock bracket for each of the 2 bolts. When the brackets were removed the old washers had either deteriorated or were never there. Is this just a neoprene washer?

Thanks Benny. On closer inspection (I took my glasses off :blush:) there appears to be a very thin washer left on one bracket. The thickness and diameter seem to agree with you dimensions but it doesn't look anything like the part on Ecklers. Maybe they have the wrong picture or p/n?

I have always just used a very thin strip of dum dum (3M strip caulk). It seals as well or better than rubber, and won't dry out. That's what you need to put around the large hole identified as 60a in the pic above. As long as you have it out, just roll out two more tiny strips for the bolt holes. Can't be seen once installed.
