Did Chrysler have rust problems with the 76' Darts, Dusters, Scamps?

My Neon's a lot better at staving off rust than any of my older cars have been. But - the brake lines rusted out and popped (that was fun) and the brackets that hang the muffler just rusted away - the exhaust is al lfactory original - it outlasted the body brackets...lol.
IMO - we've always had sand and salt in CT - now we've got liquid calcium and that stuff is eating everything up a lot faster.
