Just before cab off Jan 2017
If it were me I'd either keep looking or offer just barely over scrap price if you really want it. The most valuable part (s) I see is the a/c & related parts since you don't see many of them.
I just removed & restored the cab only + incidentals all brake related items on my 78' and I spent over 2K which included a seat from a 95', paint being the costliest along with various catalog parts and did all the work myself. Your probably saying "yea right" well wait n you'll see.
I personally feel that mine was worth it although I'm not finished rather than have a newer model and not be able to work on it myself. By the way none my $s went into the engine or drivetrain, I already did that a couple yrs ago.
Good luck on your search, the rewards are worth it, at least you'll be noticed more so than having a newer one that looks like ALL the others.
By the way where in the rust belt do you live, I'm in MI, fortunately I've owned mine since 84'
