Bracing shock towers?

Just because mopars have inner fenders people just assume that the shock towers are spot welded to them, However comma many mopars came out of the factories with the shock towers not welded at all. My family has 6 a bodies & 2 b bodies. My dads dodge demon has inner fenders, is untouched all original & the shock towers AREN'T welded to the innner fenders, same way with our dart swinger.
