I have an 81 300TD turbo
I was checking out the rear underside(for self leveller rebuilding) when I noticed some rust in the rear frame rails, mostly where they meet the cross member the differential mounts on (right next to the rear wheels)
This is the same area the brake lines attach as well as the bars from the self leveller.
In these two areas the frame rails seem pretty well rusted.poke your screwdriver through rusted..not good
IS this a ditch the car problem or does the unibody hold together despite this
It gives me pause for the possibility of towing too

HEEEELLLLLPPP!
