For half tons the running boards are all the same length. You have hit upon the bane of these trucks. Do a search and you will find ALOT of threads about trying to align hoods and fenders. Some folks spend all of their days before the committment papers are signed working on this. The best advice generally given is follow the instructions in the manual (reprinted here:http://www.chevytrucks.org/tech/AD_hood_alignment.htm ) and then just keep messing with it. Also you may want to take comfort in the fact that if you look at vintage show room pictures of these trucks, the factory didn't get it right either. Finally, as to your specific problem, you may want to try to add shims under the radiator support frame to raise the front of the hood. Of course when you do this it will probably mess up all of your other good alignments and then you will have to work on them. Most folks get to good enough and leave it at that. The factory fit and finish on these trucks was never great. Good luck
