Torsion bars

Don't know how old you are, but if you have grown up with newer cars then I would recommend a .920 or larger bar. JMO These cars tended to 'wallow" a bit when they were new. I had 340 bars on my car back in the day & I plan to go larger now.
I graduated in '78 and my first car was a '67 GTO I drove to high school...lol I'm used to non-power steering and manual drum brakes - no problem with "wallow" in the steering...lol
