All the beetle tin will fit on the type 3 once you strip off the flat cooling system and get it down to a longblock, the oil cooler works with the VW adaptor for the doghouse system or an early one bolts right to the case (check the seal bores to get the right combination), the only issue is a true type 3 case has no oil pressure sender hole so you'll have to drill or use the one on the cooler.
