Richard's comments alert me that I probably need to clarify what I mean by slightly. We're talking fractions of an inch, probably less than 3/8. And for a stock A or a '32 shell, I agree, lean back or forward looks weird. Didn't mean to imply that if I did. If you look at my '32 roadster in my gallery that was about 1/4" down.

The other point to clarify is that this fitting thing can be a bit tedious. You really need to start by shimming the body to square it up, particularly for the sake of the door and deck openings. Then as you move forward hanging parts you may have to raise or lower the cowl or the tail, or maybe do some twist to the body shell, and then tweak the hinges for the doors. And you may have to play with the fenders too. It's a back and forth process where you may sometimes feel like you'll never hit it right. That's when you want to do as Richard suggested and step back again. Look it over from a distance and visualize what needs to be done.

BTW, that fraction of an inch thing can be quite apparent to the eye. Next time you're at a rod event see how many cars are just a bit off with the grill shell too high. It seems to be especially prevalent on model A's. Once you're aware of it the upward sloping (to the front) hood looks pretty dorky.
