Chevy 235 Rocker adjuster

I've been on the phone for about an hour to various parts stores trying to find the little adjuster for rocker arms on a 59 (truck) 235. Two of the ones on this engine are crap, long past their days of adjustment. Nobody seems to be able to find this. I got a part number from NAPA but they can't get them for a week. I'm talking about the bolt with the round end that sits in the pushrod.

Does someone know of another part that will interchange?

 

Ya one off a 1958 235......pfft. I thought every one knew that.
