Best thing to do is assemble the front clip and THEN left it onto the radiator support. Bolt the radiator support on loose and then lift the clip onto the radiator support and cab mounting holes. Then insert the bolts at the rear upper fenders loose and then the bottom bolts loose. Then, SET the hood between fenders and adjust fenders if necessary with washers to get a supreme fit. I have done a few of these and this is by far the best way. Good luck and if ya have any questions feel free to send me a message.
