Anyone know what size the derby cover washers are on a Deuce? Thanks

 

Here's an answer to your question... https://www.hdforums.com/forum/gener...t-washers.html

 

When i replaced mine got the stainless bolts but got metric size washers they fit like stock ones

 

I got to get rid of them torques on my cover too, starting to strip. I think dealer has allen heads and washer conversion not sure. I think screws 1/4 x 20x1/2inch long not positive though. hardware should have also. I would go good grade . 8 maybe

 

Lowes sells them in stainless. 1/4" x 20 x 1/2" allen bolts with matching washers.
