Reciever Hitch Question

Hey, I have a question, I looked for an answer here before posting, but didn't find it. Sorry if it has been discussed before.

I have an '04 Tahoe and a friend have me a hitch from his old '04 Z71 Pickup. Will this hitch work with my Tahoe, will i need to mod the frame to make it fit? Any advice that anyone has will be greatly appreciated. Thanks...

The answer would be no. Using this tool here will give you 2 different hitches.
