Terry Cook is unsure what his plans are for the season finale at California.

Cook, 32, who drove the No. 88 PickupTruck.com Chevrolets for team owner Duke Thorson through last weekend's O'Reilly 400 presented by Valvoline DuraBlend at Texas Motor Speedway, was involved in one of the longest-running owner/driver combinations in the NASCAR Craftsman Truck Series.

On Monday, Cook and Thorson, who have been together since entering the series in 1996, agreed to end their relationship immediately. The final event in the 24-race 2000 NASCAR Craftsman Truck Series season is the Motorola 200 at California Speedway on Oct. 28.

On Tuesday both parties said they were unsure what their plans were for the season finale.

"In a conversation this morning, Terry Cook requested to be released from his agreement with SealMaster Racing," Thorson said Monday. "I granted that request. We've known for some time that Terry was looking at his options for next season and beyond."

"From the time that it became apparent to Duke that Terry wouldn't come back, he has had us looking for the right guy for our scenario," team management consultant Tim Stephens said Tuesday. "We have an idea of the direction we want to go but we have not been able to finalize our plans. We have choices in mind and it will take a couple days to confirm them."

According to Thorson, Cook's impact on the team has been major and he will be missed.

"When we started this thing, we had one truck, a couple of crew guys and Terry," Thorson said. "He worked in the shop every day. He managed the team. He did everything it took to take this from a crazy dream to being a pretty good race team.

"We wish him nothing but the best. He's a talented driver with quite a future ahead of him."

"I want to give Duke and SealMaster Racing a lot of credit for giving me the opportunity to get a start in the NASCAR Craftsman Truck Series," Cook said. "I think the biggest thing we accomplished in the 93 starts we made together was we managed to always finish five or 10 spots better than we should have -- we always seemed to do better than the resources allowed us.

"Racing in this series is tough and once you break into the top-10 it is tough to run there week in and week out without the resources. But, I am proud of the team that we ran competitively with the resources we had available to us."

Cook, of Sylvania, Ohio, had raced Late Models and Supermodifieds at short tracks in his local area prior to joining Thorson's team. His brother, Jerry Cook, is the team's crew chief and will continue with SealMaster Racing, Stephens said Tuesday.

"Jerry has made a commitment to us to remain," Stephens said. "That is some of the most exciting news we could get as a race team. Jerry is a good crew chief and he has put a good core group of people together. Losing Terry is a big loss but we're excited about the fact that Jerry wants to stay and be our crew chief."

Terry Cook made 93 NCTS starts in SealMaster's No. 88 Chevrolet. He won once, in the Stephens Beil/Genuine Car Parts 200 at Flemington (N.J.) Speedway in August 1998. He earned two Bud Pole Awards as the fastest qualifier for an NCTS event.

Cook and SealMaster Racing are currently 14th in the NCTS driver and owner point standings. In their last race together, the team finished 17th in the O'Reilly 400 after Cook qualified ninth.

Stephens also wished Cook well and said his team was anticipating making additional sponsorship announcements as well as announcing the team's driver.

"We are working toward an overall sponsorship package that we think will be pretty interesting," Stephens said. "We are very confident that PickupTruck.com is going to retain an affiliation with the team as well."
