Coil Over vs Torsion Bar

This is just a thought but I would imagine with subframe connectors, a bit of reinforcement around the K-frame mounting area, particularly the radiator support, and some "down-bars" going from the firewall to the front frame rails, chassis/"frame" fatigue shouldn't be a huge issue... Anyone have high miles on their coilover A-body riding on rough roads to confirm? lol
I have about 30,0000 on my coil over. Driven on rough roads and gravel. As said before if to do it again I would go t bar. But some have been track and road tested there are plenty of racers using them doing wheelies and that is a lot more stress on a coil over than a rough road and have heard no complaints.
