Not an a-body but your opinion on worth...

I sold my '85 W150 with the original 360 4 bbl. with 33" tires 3 years ago for $900. I had it advertised for a couple of weeks at $1200 and 2 tire kickers came to look at it, then I lowered the price a couple of hundred and the phone wouldn't stop ringing, the first guy bought it. The truck had no rust, but some fender damage when a wheel came off on the interstate. The truck needed new paint and a pass. electric window motor, but that was it. I needed the extra space in my driveway, now that I have 10 acres, I wish I still had it. BTW this is in Oklahoma.

Also, The 4WD was engaged by a vacuum actuator on the front axle. NAPA still sells the switch on the transfer case, mine was bad, and instead of fixing it, I would directly connect the vacuum line to the intake manifold whenever I needed 4WD.

Here's the best pic I got:
