They look a bit too high for a school bus cowl to me. The Hino looks too much like a Nissan for my tastes but it seems to look okay with some mods. I still would prefer either GM or Ford for BB but that's for another topic
I wonder what the 1970's Brockway chassis would have looked like on a bus or an old Mack R Series. I really wish some of these buses existed. Great job Lee.
