truck front conversion ?

I have a 93 dually that I plan on putting the new tahoe front on. I was wondering if anybody know how many inches have to be cut/ from where to make it fit.

lol... its a pain. Severed josh, he is on here but I think with a different name and he has done a few. I would say he is your best source of direct information on this topic. However, there are a bunch older threads about doing it as well. As far as I know is the only thing that is bigger is the hoods width like an inch and a half. Post lots of pictures when you get going...

I have the stuff to do mine but I have yet to work up the balls and have not decided if I should change the core support to the new one.
