73 Scamp v8 conversion

I've had a good running 360 engine and trans I took out of a 72 RV and I've been keeping my eye out for a car to put it in. I have a line on an all original 73 Scamp that is a 6cyl, auto with disc brakes and the bigger wheel bolt pattern. I've only seen pictures. Not sure what rear it has. Just wondering what all involved in this swap. Will I need to get a heavier torsion bar?
