From 1972 to 1979 the VW micro bus uses a type IV "Pancake" version of the air cooled flat four motor. Pre 1972 VW buses use the upright air cooled motor identical to the versions used in the VW Beetle's of the era. VW then experimented with a water cooled version of the flat four engine(Wasserboxer), this lasted a few short years and VW moved all vehicles to their water cooled inline and similar standard engines.
There is no 1991 VW Rabbit.

The Type 1 engine # is stamped on the crankcase under the generator support facing the rear. This # will tell you what year the motor is and the stock size if it has not been modified. ( Info from John Muir,s book HOW TO KEEP YOUR VW ALIVE)
