Noob question on options

[CC's72]

Hello Everyone, I am a new member that has been lurking for while. I have been looking for a 72 C10 for a while and was hitting all the usual places. I finally found one on CL and decided to get it.
Was wondering if anyone has seen many custom deluxe trucks with the options that this one has?
The truck is all original except for the white paint on top. The OP stated that this was a farm truck and was stored in an old barn when he received it from a friend of his grandfathers (it has the dirt dobbers to prove it, ha, ha).
The truck runs good however it needs a full blown tune up and new compressor.
I am glad there are so many experts here as I know I will have many questions coming.

BTW, I hope the pictures turn out as the one that I posted in the welcome area was turned wrong and a nice guy turned it around for me.
Thanks,
CC
