Avalanche builds some pretty sick cages, they are off Sante Fe (Hwy 85) and Titan Rd. Not sure how much you're looking to spend, though. Another way to go is to use the Smitty built as a starting point, last time I priced them the roll bar was $150 and the front kit (weld-on) was $90. I'm assuming you know the floor is different in your's than the factory full convertibles. Not that I think it's a strength issue, just saying the same cage won't fit.
