Width wrong in IE6. Please help.

You can find the page at www.vciparts.com (http://www.vciparts.com).
Please take a peek at the CSS and point out my folly :)

I can surely use another set of eyes on this. If you view in old IE, the footer and content widths don't match, and I can't find why. PLEASE HELP!

FYI: The footer is actually correct. The content is supposed to be centered.

Thanks-a-bunch,
Mo

Fix the errors in your markup first, see http://validator.w3.org/check?uri=http%3A%2F%2Fwww.vciparts.com%2F&charset=%28detect+automatically%29&doctype=Inline&group=0

try adding different background colors to each element to help see whats going on
