Dufault, now seventh in the driver point standings through two races, is in the middle of planning a June wedding.
"It is going to be June 28," Dufault said. "That was the only weekend I had off from racing that I was able to squeeze it in. It was really challenging to pick a date."
Dufault, 32, is a native of Sorel, Quebec. She will marry Guy Zubchevich the week between ARCA Racing Series events at Elko Speedway June 21 and Winchester Speedway July 6. It will take place in a town about a half-hour from Montreal, Canada.
"We've got people coming from all over," she said. "My fiance's family is from Arizona and California. There will be people from my team and people I've worked with. It's going to be a really fun wedding."
Dufault's No. 46 Stange Racing team is off to a good start in the ARCA series. She led laps in the season opener at Daytona International Speedway and finished 16th in the Shooters Restaurants-HotTVBrands.com Ford at Mobile International Speedway in her first race at that track.
