Need to ID rear air shocks.
 

Bought a JacPac 175 to install in cabin air shock control on my 68 El Camino. Posted here:

Now I need to ID the rear shocks. As stated, box was marked with felt tip pen as being for a 1970 Chev. P/U. Been a long time since I looked under a C10. Should be the same 67 to 72, I believe. Although, seems I remember some having leaf springs and some having coils? Surely they wouldn't use the same shock, would they?

Here is what I have. Overall length as it sits is just over 15 inches. I can compress it about another half inch if I push real hard.

Just need to verify what these fit before I try to sell them. Tried looking up the stamped numbers, but no luck (fwiw 4964646 followed by P3646LR).

Any of you guys have a 67 to 72 C10? All the shocks I look at for those vehicles have eye type mounting top and bottom.

Anyone tell me what these fit?
