slide out bolts/spacers

[campnfish]

Hello all!

Has anyone ever lost one of the shoulder bolts that connectes the bunk slide-out to the rails?  There is also a small plastic/nylon washer and a larger one well (~1/2in thick).  I have tried to find relacement bolts (exactly like the other ones, but haven't had much luck.

What you anyone reccommend for both the bolt and the washers?  Or will just about anything actually work.  I just want to be sure...

Thanks for you time and help.
