Ya have to order them from LMC or Classic, they just slide in with a little lube in that channel and basicaly just keep themselves in there once installed.
They just look like an xtra windshield wiper blade with a thick back edge that slides in the groove and locks itself in place.
YUP these old trucks can be fun!...lol..waited for another weekend myself on a parts order for little things like the wipers, so I guess ya best get an order in an get a pair before ya proceede as the glass at its lowest point stick up just enough to cover the groove and make you have a bad day.
