What is the easiest way to get fields to right-align in both IE and Firefox?

Hi,

I've got some form fields where the right-hand side lines up correctly in IE but in Firefox the alignment is off. I'm using a combination of the size property and spacer gif to accomplish the alignment in IE. What is the easiest way to get the right-hand size of the zipcode field to line up with the right-hand side of the address lines?
