1978 K5 Blazer - Are these factory wiper arms?

I ordered a new windshield for my Blazer because the current windshield has a crack in it.  While looking at the windshield I noticed the wiper arms and I don't remember ever seeing anything like these?

Are these the factory wiper arms?






This is the part I don't ever remember seeing on any type of wiper arms?  It's the screw?




What's the collective consensus?

Those look like early ANCO arms...

Someone couldn't figure out how to put them on and used a screw. OER sells period correct wipers if they are screwed up from whatever the knucklehead who put them on did. Part # *r868

Nah, those are the old 4103 Anco's....the full serve station I jockeyed at while going to school sold them, I've installed more than my share.

[VileZambonie]

Yes, you are right. This is how they should be installed, reference that part # I posted for correct setup.

Thanks everyone, you guys nailed it.  It's NOT factory - but a replacement.

As long as it works, that's the key thing.  I think I'll try to polish the aluminum while I have them off for the windshield replacement.
