I have sat in the Bimarco Futura (tight) and Bimarco Grip (snug) I am 6'2" 240# 36" waist and wide shoulders. Compare your measurements to mine and the Cobra to those seats. Note the Cobra is not FIA certified and is 3-4 pt harness only, not an issue if using 3 pt belt.
Easy mounting? Get a set of OEM sliders and extra seat belt receptacles from Woody and a pair of planted or sabelt universal side mounts and you should be good to go, possibly even with no drilling
