Torsion bars for stock suspension rebuild

I am rebuilding my 69 Barrracuda front suspension and have noticed that most of the advertised torsion bars (Mopar Performance, Just Suspension, ...) are selling replacement bars that are thicker in diameter that the originals. Most are 0.92. Has anyone had experience with the thicker bars? Is the ride to firm? What shocks work best with the new bars? I am rebuilding the suspension to stock as a week-end curise and show car.

Thanks
