Help identifying shocks
 

I have a few shocks I’m trying to find out what the application is if anybody can help me out greatly appreciated
3192293. 005 1970
3197691 187. 1970
3199248. 012. 1972

Nothing showing up in any of my old Chevrolet parts counter books,sorted individually from 1965-1980.But that doesn't mean they're weren't used on a Chevrolet.
Shock part numbers can be very mysterious to ID.
