Trying to find a different center section out of a different truck could work as a whole other brake to brake out of different truck. Most med duty's (exc [Edited by Moparts - Family Friendly Site - Keep it clean]) have the same width frame rails so the perches could be the same. That 361 should be governed around 3600-4000 you wouldn't want to rev that 15" clutch much higher than that. Most of the later stuff wont have a splitter though.

Perhaps Asian would be a better term today
