I'm going to junk my 78 450SEL. Before I do I'd like to strip it of the parts that will fit my 75 450SE. Will the 78's electronic ignition unit and ECU work in my 450SE? Since the 75 is a D-Jet I assume that the ECU won't but the ignition unit might. How about the radiator? Will the 78 's fit the 75's? Can anyone think of additional parts that may work in my 450SE from the 450SEL?
