Original CST option bench seat? 1970 C10/400
 

Hi Folks,
I am slowly rebuilding my 1970 CST C10/400 SWB...

The original interior is a pretty cool green on black. Haven't seen too many in this combo. The seat, however, may or may not be original. I say this because it had a build sheet in the springs that do not match my truck. You never know why changes are made over 44 years so I am throwing up a few pics to get your opinions.

FYI: I do not have a SPID or complete (current) build sheet.

As always, you guys rock!!
