1969 C20 front shock question

[neirfin]

FWIW this might be worth moving to the 'stupid question' section if there is one...

I searched the forums and the internet in general but couldn't find an easy answer... Checked LMC diagrams and images and can't find this bolt. It is supposed to be holding the shock to the frame, i assume... i got under the truck and noticed the drivers side is not connected at the top... based on the passenger side, it doesn't look like there is a bracket, just bolted to the frame.

Is this bolt available and just not in the shock section of catalogs/websites? When I ordered replacement shocks, they each only come with one bolt? are the top and bottom bolts the same? are they to be reused? is there a missing part where the frame is that the shock should bolt to?

TIA!
