putting in used engine in Dodge D-50
needed new engine in Dodge D-50 1990 4 wheel drive. Found used engine in Dodge D-50 2 wheel drive - 1991. Measured motor mounts - both the same; both engines 2.4
When putting in the engine into the 1990, right side bolted down just fine to motor mounts. Left side 1/2 too high. !@##%$5! any ideas, do I need to change out the oil pan?
