NJT Transit used many coaches from various railroads, behind the E8s. They were often old Budd built long distance coaches Some were still in their predecessor paint schemes (BN for example) and some were painted NJDOT or NJT.
There is a Facebook group about the NY&LB/ North Jersey Coastline that has many discussions and pictures of the NJT E8s pulling interesting consists. You might get some ideas from their site...
