Help Identifying gear set company

I bought this gear set used; they said they were for a CJ Jeep. After trying to set up gear to get a good pattern, I am not so sure. It is an AMC 20 in a 76 CJ narrow track. I need help Identifying the gear manufacturer so I can run the numbers.

Not sure on the manufacturer insignia(I've seen it before but can't remember the name it's associated to), but you may have to get a different carrier for the 4:10's on a model 20, depending on what gears you were running before... Give Randy's a call & ask---they'll know.

Antonio Massiero is the builder.
