FB Width Problem

I am having a problem with resizing the width of an FB generated form into my current template. The original form can be seen at customquote-original.php. I had not yet applied any security features to this page, so I didn't have to remove any coding ahead of invoking FB.

After invoking FB, I get what is seen at customquote.php, which has lost a lot of formatting. I know that I need to "re-bound", i.e., re-input, each field's label , which I will do. (Hopefully, the next version of FB will eliminate having to do that since that can be quite time consuming.; it will be for me as I have multiple forms that I am converting.)

However, I need to know how to get the FB generated form content to shift to the left so that all the information will be shown more like it is shown in the original page. I have tried within FB to change the form's width from 820 pixels (the value shown within FB) to 608 (which looks like a good value for my form) and even to 900 (to see if there would be a difference), but I see no visible change in the layout.

Any advise would be greatly appreciated. Thanks in advance.
