Hi everyone! I am new here. I am working on my buddy’s 70 Charger that we are converting to a 69 General Lee. Don’t worry the car was a shell missing everything! It currently has a 1977 440, is there any difference between a 77 and say a 70 440 as far as what external accessories can be bolted on like power steering pump, alternator, crank pulley, distributor etc? Does anyone else sell repop parts besides classic industries? Thanks!
