Need some info from the GMC guys

[zellway]

So in talking with a friend the idea was hatched to swap the front clip back off my Sub for the 67/68 GMC front. I got the core from a 69 gmc with all the wiring and headlights with all the hardware. What I need to know is if this will work for my plan. My Sub has a full 68 front clip so the hood and fenders will work but I don't know if the core will work. I know in the chevy's the headlight are mounted on a base that moves them to fit the 69-72 depth grill. I have no money in it at this point so if it will not work I'm not out anything. When I get home I can get pic's for what I have. I'm just looking for some info on how to ID what I need. Any help would be great.
