I'm installing the 4 speed and the engine as a unit from underneath. I've hit a snag with the trans. 70 Dart 340 was originally auto, now converting to 4 speed. I have the rods and shifter aligned and adjusted perfect and mated up to the trans. I'm lowering the car onto the assembly, but I don't see how the rods clear the cross member. I know the reverse rod goes under the cross member, but do you have to run the other two through the hump hole? Meaning the unit cannot be assembled for installation? Sorry if this is confusing. See pics.
