Wiper arm/blade help

What wiper blades and arms are for a 57 3100? I picked up a set of blades from LMC and I can't seem to figure out how they would be connected to the arms currently on the truck?

thanks.

 

nobody? Somebody has to have a PN or a tip!

 

Wiper Arms

Hi Bob ;

Maye a photo of what you have , both wiper arms and the nubs they fit upon , will help .

I'm 3,200 miles from home and way backed up on E-Mails so expect slow replies .

 

Thanks Nate,
here are pics of the ends of my wiper arms and the clips on top of the wiper blades. The wiper arms were on the truck, I bought the blades from LMC.

 

O.K. Bob ;

You have the wrong blades for the arms is all .

Those blades are to fit wiper arms with little spoon shaped ends .

Maybe look in NAPA's ' classic ' wiper blades OnLine ? .

 

Thanks Nate!
