Thanks a lot. I looked everywhere.

Neat timing. I just pulled my Robinson's out and used them on a trans rebuild for the safety wire.
They are old, but they work great.

My brother works on jets and planes and I'm going to give him these. See if he knows. I am almost sure he knows what these are.

Oh yes, an A&P will certainly be familiar with them.

Those wire twisting tools seem popular in aviation

Just a quick pic of mine because my current project requires some safety wire.

What is that? That requires safety bolts?

It is a New Process 420 4sp from a '54 Dodge 1 ton. That is on the Parking Brake on the trans. That bolt is an adjustment that helps pull back the band from the drum when it is released, but the adjustment is held in place with safety wire from the factory. Same thing for the front countershaft bearing retainer and the shift forks.
