Ohhhh.....dangerous question.....asking me about VW's
Split screen vans were made from the early 50' until '67 - aircooled engine - split front windscreen, small rear lights etc.
Early bay windows from '67 (smaller bumpers, smaller rear lights, lower indicators at the front, aircooled engine)
Late bays from 72/73 - 2006 - (larger bumpers, larger rear lights, larger rear air intake grills higher indicators at the front, aircooled engine)
late late brazilian bay from 70s to 2013. Made in Brazil. smaller bumpers. aircooled until 2006 then changed to a watercooled 1.4 Polo engine, which meant adding a slightly iffy radiator grill on the front.
YOU CAN WAKE UP NOW EVERYONE!
