Skyler Nelson,
First off, welcome to the Stovebolt Forum. I am the probably not the best person to ask if a Pontiac LeMans front end is a good fit for an AD Truck. I am more of a period correct kind of guy. However, I do understand the allure of modifying them. Some of them turn out great. Then, there are those that aren't so great. On a personal level, I have seen a lot of modifications done, including cutting off the old and attaching a new front clip/suspension. There is a whole lot of room for error. I would be cautious, when it came to purchasing something like that, without inspecting it very carefully first. Some of the other guys should weigh in soon, on the matter. Be careful not to let your enthusiasm get in the way of good judgement. Good luck with your decision. Hopefully, this advice, and others suggestions will help you.
