Roll Bar Option

I follow a bunch of Scout people on Instagram, some of whom are prolific posters and use it to their advantage. Others are quieter but show off some good stuff. I’ve been aware of GRC Fabrication from the Binder Planet but haven’t really done much investigation of their products until I saw a post with their Scout II rollbar. It looks pretty good from the few pictures I can see, but I’d like to know how it mounts to the floor and where. If the front legs mount the same way the factory bar does (folding down the front of the step) and use the same bolt holes, I’d consider buying this to replace my rollbar–and adding rear seatbelt hookups for Finn. The price is right; I just want to know about the mounts and how strong the bars are.
