I like the look of an 8 ball shifter myself, although dan, I'm not sure it fits looks wise in a contour. 30's ford or 50's chevy, yeah, but 90's sedan? I just don't know.
I think your biggest problem would be the button on the shifter you have to press to get out of park. With some internet seraching you may be able to find an 8 ball shifter designed to work with an automatic. I'd recomend some of the companies that supply more to street rods and hot rods, like Gennie shifter or lokar. But again, I'm not sure how good it would look. To me it needs to be on a long shift lever to look good, like chrysler did with the PT cruiser. Let us know how it goes (even if most of the guys on here will flame you instead of help you)
