help please,4 speed conversion qusetions

Everything will fit, IF it really is an a-body four speed and wasn't cobbled into the Dart. The 130-tooth flywheel is NOT the big one, it's the middle-sized one (I'll let you pull the 143-tooth flywheel out of my son's Dart next time...........). Also make sure the four speed is not an overdrive, unless that's what you want. You will also need the floor hump.
