74 to 89 Front Clip Swap on C30????

Hey guys... just picked up a clean 1974 C30 dually. I don't know to terribly much about these trucks, and year to year fitments. How hard is it to convert to the 89 fenders, hood, and grille/headlights? I know the big difference is the fact that the 74 has a much different hood hinge and cowl panel setup. Any input?

core support is the only thing you are forgetting.

Sorry... I knew that was a part that needed swapping... I was asking how much work was required outside of bolt on parts. The fenders, core support, grille, and headlights should bolt on correct? I'm just left with hood and cowl issues? How bad are they to get fitted?

everything will bolt up but u might have to trim the frt frame horns to clear the frt bumper and cut the cowl some for the hood hinges thats what i did when i went from a 78 to a 89 burb frt end
