Doug's '68 Dart

I don’t think that inner fender brace will work at all.

Mock up a tube hugged against the inner corner and should connect directly to the RMS upper spring mount where the load now is.

more just stick it inside the engine compartment

Hmmmm…. if the shock mount is moved, thus transferring the torsional twisting to the frame rail & k-frame, what does tying the fender to the shock tower actually accomplish? You may have a point. This would also make the core support make a little more sense (tying the two frame rails with a little more strength).
