[&:]Late but if in case you still haven't find one... I got the replacement for my Dodge roll bar here:

This website has a HUGE selection of roll bars of all styles, including my favorite, the HB roll bar which mounts via rail so one could also have a tonneau cover. Only downsides I see are price and available colors (black).

 

Do not throw away money on jcwhittney. Find a local classified website. Around here it's pennswoods, lots of hicks like me over here with them, tons for under 100 bucks
