Hi I have put an m110 engine and auto trans. out of a (1977 slc ) into a 1981 380sl.... Does anyone know what I will need to change out electrical wise if anything, to make it run?...I already have the engine and trans. changed and bolted in...I have spark and fuel ...but it won't even try to hit...also I do not have the car that the engine and tranny came out of...will buying a new flex plate for the swap fit the 380 driveshaft?...thanks!
