I'am thinking about do a trade for a 34 ford 5 window coupe ,all steel body.This would be my first street rod of this type. Does the 5 window have more room inside then the 3 window ? I dont see many 5 windows out there are they harder to find more in demand ? I would like to know if there is any adavantages with a 5 window. It has a stock mustang II front suspension with 2 inch drop spindles and 4 wheel disc brakes. It all done up with all the goodies.
