I also installed the Breeze roll-bars (I have the stainless-steel version and considering having them polished) and REALLY like them for the reasons you mentioned (shorter, fatter, angled, no bolt on rear leg). I also installed my high-back seats to follow the rollbar angle, looks better!
During my build, after go-kart, I temp installed the roll-bars and drove the car to a local shop that welded stainless-steel. They put 3 small temp tacks on each bar, I drove the car home, removed the bars, took them back to the shop, then they did a solid weld completely around each bar.
I re-installed them and marked where the body was in the trunk on the rear legs. When I took the body off for paint, I installed them again and drilled all of the through bolt holes. Just an FYI, I burned up 2 brand new drill bits, drilling those stainless pipes, they are pretty tuff!
I also contacted Russ Thompson and he fab'd up a set of grommets (in-fact, mine was the first set he created and he sent me a proto-type set to try on my roadster before fabbing the first finished set) (Thanks Again Russ!)
Your build looks great! Really like the Coyote and the black wheels look good on there (very baddazz, if that's the look you were going for, you nailed it). Are you going with black accents? (side-pipes and roll-bars)
I also want to thank you for your service and stay safe!
