well i have some. but depending on what your end results need to be, there are about 5 different bus makers. each one has several sub models and configurations. one of those makers puts their side rub rails in a different position every year.
if you need something ultra generic and generally wrong i could toss something your way. or if you have a specific model i can see if i have one for that one.
i have a lot full of short school buses and no 2 are the same.
