yes and no the washers on the clevis will probably work just fine however the eye rubber is supposed to have a steel insert in it if it does not then great go ahead and drill it but you might want to go to a farm supply store or hardware and get a roll pin, pipe, or bushing the right size for the stud that it mounts on and glue it in this will increase the longevity of the shock rubber dramatically as well as having a good place for a little lube ( inside the roll pin or pipe that you use for a sleave ) this will help stop the incessant squeaks from the rubber
truly the best material for the sleave is a bronze bushing however they are exspensive and other than not having to be lubed from the start saves nothing
if you put a sleave in the rubber be sure you use a large washer on the nut side of the stud through the eye or the nut could pull out the sleave
I use locktight 722 with a primer to permanently lock the sleave to the rubber however any locktight with a requires heat to dissasemble will work
if it does have a sleave in it and it is too small then drill into it a little and use a torch to heat the drill bit after you conduct enough heat to the bushing to free it from the rubber the bushing will spin out with the bit
