I just got a RUPP vw powered trike but not sure what it is all about. The guy i got it from said it was a 86 rupp body and a built 1300cc motor but on my search i think the body is a 73/74 centaur with a 1600 dual port type 1 engine #AH196046 . can anybody help me with my findings? Well tried to upload photos but site will not let me figures
