I have a 1971 FJ40 with the vacuum transfer case.. I had to put in a Jan. 1972 engine from an fj55. Does anyone know what I will have to do in order to get the transfer case to work? My old engine looked different (there is a port in the manifold on the earlier engine that is not on the '72 engine). As you can probably tell from this posting I am pretty low on the mechanical learning curve. Would appreciate any help anyone can provide.
