1966 K10 shock recommendations

[davee60]

Once again, I turn to this excellent forum for assistance!

I am having a heck of a time finding definitive part numbers for front and rear shocks for my 1966 K10 Suburban project. I would think that they would be the same as the K10 pickups, but all the vendors I have searched (Jegs, Summit, Brothers, Rancho, Bilstein, etc.) do not list a specific shock for the 1966 4X4's. Am I missing something, or do I just need to measure? The old ones were so rusty and trashed that they went right into the junk pile, in hindsight, a mistake on my part.

If anyone has some brand and part numbers that I could cross-reference, that would be great. Thanks!
