1965 Dodge Dart 270 2 dr sedan

I can't answer your question on the coupler or torsion bar as I never got that far. On the filter adapter. Are you going to use the factory right angle adapter or the remote adapter? I should have one of each style. On the throttle cable, I would probably wait until you have the intake and carbs installed as I suspect you may need a custom length cable. I have a matched set of water pump and crank pulleys, but they are still installed on the 273 in my Barracuda. I will be converting the new motor over to a multi belt system as I will be adding aftermarket AC. Cannot help on the transmission cables
