Stuff worth saving?

[CG]

First off this is absolutely not a for sale or a fishing expedition. Im just trying to establish if this stuff is worth putting away. 1967 and 1969 C10 clutch pedal assy and associated parts. I have no idea if these are year specific. Can they be used on all model years to go from auto to manual? Rare to see done I know. Is it the same on 4x4? Cross members?

I'm getting down to the bones of my 67 and 69 parts trucks, don't want to regret tossing something.
