Interesting…but false:

from the AutoRacing1.com site – rumors section [need sub to read] – CART to sponsor Winston Cup car: AR1 spies have uncovered secret schematic drawings of the paint scheme of a possible CART Champ Car sponsored NASCAR Winston Cup car (click to enlarge). This is marketing genius at its best. With NASCAR’s popularity, we can’t think of a better way for CART to gain much needed exposure for its Champ Car Series with millions of race fans. However, we doubt NASCAR would allow such a thing unless they were allowed to sponsor a Champ Car in return. Why not? We don’t hold much hope that there’s a lot of truth in this rumor. UPDATE from AR1: This rumor is downgraded to ‘false’ as we suspected it would be. We heard from someone connected with the #91 car who says they know nothing about such a sponsorship, which is too bad because there was a lot of reader feedback on the concept.( AutoRacing1.com )(9-21-2003)
