Some time ago I bought a set of hood latches for the 3A. They looked to be identical to the set that came with the jeep. One of the originals had separated from it's mounting base and the base was broken slightly. This was in the pre-welder days...
But now as I clean them up I see they are different...

The replacements are just a little taller...

The biggest difference is the flattened portion of the barrel on the original latch...

I'm going to use the ones with the flattened barrel, as they came with the jeep, correct or not....I'll repair the base..
Do you suppose this is just another case of they used what they had on hand or are there lots of different Willys latches?
