Some of the larger trucks and motorhome chassis with BB motors had the emergency brake on the trans, not on the rear wheels. As long as the tranny your getting has the long output shaft, not the short one with the emergency brake on the tailshaft, and the standard type slip in trany yoke and Ujoint you should be fine
Some of the cars and trucks had a two piece driveshaft that the front Ujoint bolted to a fix tranny output yoke
Any of these trannys can be converted to passenger car use as long as you have the parts needed to convert them
