T-bar clocking ?

I am getting ready to purchase new torsion bars for my 67 notch. I have checked my options and I am concerned with the potential clocking issues with aftermarket T-bars. I want stock ride height so no lowering options required. All information will be appreciated.

Clocking can be a problem with the really big bars. It shouldn't be a problem with any of the popular sizes but it is a good question to ask when buying heavy duty bars.
