Talked to Joe today and got my order in...
After looking through all the photos of the summit page I found one that shows the roll bar mounts. (last photo of the differential section) There are two brackets welded to the frame plus they're at different heights so this is not any easy add-on.
Now that I've learned how differentials work it should be a cake walk. (especially since they're putting most of it together)
I figure I can handle the fuzzy dice mounting on my own.
