when I pulled my shocks, there was a metal bushing that fit in the rubber bushing of the shock, then two fender washer on the outside of that metal bushing(center hole big enough for bolt but not for the metal sleeve) then a thicker metal bushing/spacer on one side...or maybe both sides, can't remember exactly now, but there was definitely some washers and at least one thick spacer
my shocks were aftermarket, yellow, probably just Monroes, the truck is an '85 as well
hopefully that helps at least a little
