Rally Tops making older CJ5 Tops

http://www.rallytops.com/jeep/cj5.html

I just saw where Rally Tops decided to make Pre-76 CJ5 tops. I don't know where they get their rear range distinction though. They have it split into 2 groups:
55-71, 72-75. The only thing I can think of is that they are under the idea the bottom mounted wiper came out in 71, since the top mounted wiper winshield is a little taller. I sent them an email about this, but I got some generic copy and paste response that didn't answer my question.

In their mock up pics, its got the upper door hinge way too high. That's how the 76-up doors were. If they intend to make it so the Bestop hinges work, they need to change that

 

More than I paid for the Jeep! Nice though...
