Both of those came in 2002, when he drove the #45 truck owned by Petty Enterprises. Clarke, despite his stock car inexpierence, did a good job in his races. In his debut at Richmond, Clarke started fifteenth, drove a solid race and ended up 23rd. Clarke then moved onto South Boston, where a 16th place start led to a twentieth place showing. Despite Clarke's promise, he was never picked up, and has not raced since.
