New to me '73 Maverick 302 Manual trans, Northern VA

Get a new Champion 2-row radiator and a shroud. Cooling problem solved. The radiator that's in there now is probably old and the passages are probably partially blocked with corrosion.

Definitely do a front disc brake conversion. Make sure the rears are in good condition and adjusted properly. Make sure there is no air in the system.

Get some wheels & tires that actually fit the car.

 

I couldn't agree more. The rear wheels that the guy who owned it before me are cool and everything but certainly do not fit and there is some tire rub from body roll.
