I'm trying to convert my 4th gen hb hood, headlight assemblies, and front bumper to fifth gen. Im shaving the corner lamps and using the stock 4th gen fenders which I have flared 4 inches. Will I need to change the core support. before doing this or is it a direct crossover. Are the hood and lights direct bolt on? I would check the junk yards but they don't have any 5th gens where I live, to take the needed measurments. Thanks for any help with this prob.
