Came across 2 of these adapters, don't know what they fit... can anyone ID them for me. Like to move them, once I know what they are.

I don't have an Offenhauser catalog in front of me right now, but that transmission pattern looks like early Jeep.

 

That is Flathead to Jeep T-90 3 speed 4 wheel drive tranny

 

THATS RIGHT! Just looked in Dad's ancient Offy catalog! Exact description! Says they weigh 12 pounds too....

 

I had the same one. never knew what trans it used till now. thanks

 

Are both these adapters sold now?
