Finally attempting to update this thread - turns out having 2 kids under 3, full time work, house renovation projects, and trying to restore a vintage car is a lot for me to handle.
It was clear for a while that Pearl's rust wasn't something feasible/economical to tackle. I somewhat knew this from the start, but as I got it to a reasonably reliable driver state, I never felt comfortable with the integrity of the rust enough to drive my wife and young kids any real distance or speed. I had looked in to possibly doing a frame swap, but without a lift or space to house a severed body/frame, this was ruled out. So I decided to hunt for a clean body and frame, mostly trying to find rollers to swap Pearl's healthy drivetrain in to.
After lots of near misses, in March I found a seller out in Western NC who had posted an 84 for sale, and reached out. The truck is originally from Oceanside, California, then owned by an older gentleman in Tennessee who did some restoration work such as replacing the roof skin, interior carpet with Noico insulation underneath, and some other minor things, before letting it go to the current owner who never found the time to complete some needed things. The truck had 174k miles and all stock under the hood except for aluminum radiator. Known issues were rust on the windshield corners, slipping clutch, and some oil leaks. I talked with the seller for a while but with a newborn at home, couldn't find the time to make the 3 hour drive to go see it, and the seller was asking quite a bit more than what I could swing or thought was accurate. As luck would have it, it remained available, and made the drive out in April to see it and landed on a price.
Pics from the seller's listing, my inspection, and the drive home. (No, not moving, but had to rent a tow rig and the box truck was the smallest U-Haul would let me do it with).
