Jack, I have to say, your friend that helped you may have "done quite a few" frame clips, that doesn't mean it's done right. To make it "look" good is secondary, to have the steering and suspension geometry correct is most important.
I have seen front clips that "looked" good, only to find they wouldn't even come close to a proper wheel alignment. The understanding of basic steering and suspension theory in needed to make such complex design changes. MOST people who have done all these THOUSANDS of frame clips don't have this knowledge. That scares me to think they are on the highway with me, at the very least, they have a car that has less handling qualities than it could.
This is not to say a Mustang style kit is going to be perfect. I personally got one from Michael Thomas enginering for a Stude I did that had no anti-dive built in. They had redesigned it for some unknown reason to eliminate it. It was also poorly welded AND the welds were ground down to nothing. I sent it back and got a Heids, it was beautiful. The TPI is a copy of the Heids from what I understand.
My point being if the Mustang II is from a respected company, it will be designed and install correctly with ease. The original frame doesn't get cut in half and it even "looks" good.
