68 Barracuda Fastback -best fitting roll bar?

I have a 68 Barracuda that I have tied up all the unibody/floors and tubbed the rear wheel wells. I'm installing a RMS front suspension, 6.4 Hemi, Tremec 6 speed trans, Cal-tracs and a shortened Dana rear axle.
I'm Looking for any recommendations for fit and quality to put a 6 point roll bar assembly with removable front bars in my car.
As with anything it always seems the rule is to pay a little more up front for less headaches at the end. LOL
Thanks ahead of time for any help!
