So, while tinkering with my ’83, I found a Schrader valve on the driver fender under the hood. Traced the lines from it and found red air springs installed inside of the front coil springs. I assume this is front load leveling installed meant to help when the plow is attached, since that thing is super heavy. Anyone know a way to identify what springs they are? Or perhaps know of a writeup somewhere that details what would be needed to modify it to use a compressor mounted in the Bronco…
