Body Mounts. Energy Suspension or standard?

[66x3]

Am I the only one who has experienced this? I went to replace front cab mounts on my 66 C 20 ( with rubber) and found the top of the frame mounts rusted pretty much through. The older gent who bought this truck in 73 said " It never spent a night outside" and the truck was zeibarted at some point. I'm thinking the nights sitting inside caused this? Long story short what started as a pretty simple job got a lot more complicated.

That is weird.

Have you managed to repair the damage without resorting to taking the body off?

Humidity is really pervasive. Having spent a lot of time working in Michigan, I can certainly understand the corrosion. I usually put a thin film of lithium grease on the mating surfaces of the bushings to help slow the moisture from making its way between the rubber bushing and mount.

I'm in the process of welding new metal on the underside of the mounts, ground out the circular rusted areas and have a big washer recessed into that area and one of the square shims on top of that. The original mounts had one shim when disassembled so thinking it should sit about right. The rear (underbed) portion of the frame is a little crusty so pretty sure thats what caused the rusted mounts. The old truck is still in better shape than most michigan vehicles that age. Guess i'll see if my welds hold up !
