I have not exactly like yours but same size and mine was an addition for hang on ac on my 73 340 Duster.

Possibly for add on A/C?

 

[oldkimmer]

Yes, I didn’t even think of add on a/c. It fits inside the other pulley perfectly. Thank u guys very much. Now I’ll measure the bottom pulley depth and see what years they fit. Double crank is 3 deep x 7 1/4. The other is 4 deep x 6 5/8. Kim
