The following pics are prototype conversion poly motor mounts that will enable a pre-magnum LA small block to be used in a 1997-2003 Dakota. (The HiPoTek Crank Sensor Adapter will also be required in most cases for this swap.)
Note: There is a difference between some of the LA block versions (318 LA, 340 LA, 340 LA replacement, 360LA, R3, 5.2/5.9 Magnum...) in regard to the driver's side LA style motor mount bosses. Some have narrow bosses and some have wide bosses.
