The arm in your images appears to be a later model vehicle replacement.  Looking at the one on KW website appears to have the "bayonette" end (I think I'm using the right description).  To use that arm, it would be best to get their wiper blades - assume that they would match.

From what I've seen,  the original arm had a flat end with a slit in it.  The blade had a vertical "tab" that would slip into this slit.

See example here:

I don't believe the 3B ever switched over to the more modern style that slipped over the to of the nut - but used the acorn nut that held the arm to the shaft.

yes , i bought there blades at kw, and they are a exact copy of mine. so that part is a go. with these old jeeps they have owners who   reused parts form other willys . so i was trying to find a starting point. thanks for the info, i'll read that thread. and post pics of my wiper motor.

Good pictures.  If I'm seeing it right, your arm is the type I've described; slips onto the shaft and the acorn nut cinches it down.  I think I even see a bend in the arm out near the end (image #1727).  So for the exception of the tip and how it connects to the blade, it seems very similar to what I have come to believe is the correct wiper arm. 

Going back and looking at the KW example closer, it has the newer style of connection to the shaft that I was describing (nut on and then the arm clips down on top of that nut) - see the second image in their listing where it shows the arm at the base flipped upside down.  That's closer to what I had when I got my jeep.  A PO had gotten a wiper from somewhere and made it work.  I would just swap out the wiper blade rubber insert (at the time, they were just $2 and I got two out of each insert) and keep on going.

**One thing you're forcing me to do is go into the garage and look at what I have to help me remember....*

I knew I had a chrome arm (advertised as replacement), a new original style and a used original.  The chrome replacement was shorter than the original (see below - shows original used compared to shorter chrome replacement).  The new original style arm was listed as NOS.  So naturally, I bought one and it matches the used original perfectly.  I'd forgotten where it came from but luckily for me I put it in a bag labeled "NOS from Pete DeBella"  so a few more types on the keyboard and here is his listing:

He also has NOS blades too.
