hey guys digging out some pictures I have a question regarding my 400 4 sp. fbird seems pretty rare its def 4sp and dual traction arm rear end its champagne in color s-s ( I think not common ) and hood tach car, but how many 433 rear ends production? I'm checking this now as I am restoring it. its pretty cool and super condition. the motor has 670 heads but this is very early production car..the car is apart but have just about all I need
