I know a guy that just bought one of these. I went and looked at it and it was square, I'd add some fish plates though. Then you can buy the biscuit style engine mounts and a tranny crossmember. Body mounts are easy if you can weld and if you can't you might as well learn if you're building a car. The rest of the components can all be bought in kit form from a place like Speedway. Just an opinoin, a lot of these guys will know a lot more.
