I need wiper bushings BAD!!

Can anyone point me in the right direction on where to find bushings for my windshield wiper linkage ? or does anyone have some for sale on a parts truck ? I posted this at For Trucks Only, but I know a few folks here enjoy these great old truck here. :D
Thank you for your time on this, it's hell trying to drive in this Arkansas weather this time of year, my wipers work but all the clips that hold the linkage together under the cowl are gone and I am using washers and wire and we all know what that sounds like and the wipers don't make a full pass.
I have look high and low with no luck.
