Welcome aboard.

Based on the way you state the question, I'm going to guess you've never done a frame or front clip swap before. These are both fairly complex operations that amatuers should not tackle if you ever want the car on the road again. If you have some good friends who have done this before, not just thinking they can do it, then it's a different story.

Here's my suggestion for increasing your odds of success. Check out www.chassisengineeringinc.com they have parts pre engineered to make the modifications you're proposing.
