Cool find and cooler post KDAWG. Now let's see if we can find the owner.
Guessing since the manual got separated from it's original horse, the original owner no longer has possession for whatever reason. Be very cool to find a new owner, especially if several times removed.
I found the original rear seat to my '71 by accident when I stopped in to see a previous owner who'd accidentally left a gas card receipt wadded up in the hinge of the glovebox. Recognized the company address so dropped in on them just like a stalker! One of the guys at the shop said "hey, I think we have your seat up on the top of the office. Want me to go get it?"
Uh, yes please!
