.92 to 1.03 bars

Have a 67 Dart with .92 torsion bars. looking to upgrade to the PST 1.03 bars. Has anyone done this?

I have a set of the 1.03's but I havent installed them yet, and after thinking about it, I may not because they wont give as good weight transfer on launch. I have actually been thinking of stepping down in size to the /6 torsion bars.
