except for the wrong flavor motor

Have you fitted and squared-up the front clip? I wish I had a nickel for ever hour I have spent trying to get the fenders, grille, hood, and side panels to line up nice. I bought one of those import repo. grillles, and i have regretted it since. It was so flimsy and thin, it's rediculous. After I got everything square, I discovered that the left headlight opening extends about 3/8" further forward than the right one. It's not noticible, but it drove me nuts trying to shore everything else up.

I had to extend my hood about 1/2" too.
