Since the car is from Tulsa, the car would have been raced mostly in the SCCA's MidWest Division. Most of the MidWest Division tracks from that era are long gone. Some of them were the park in Ponca City, Oklahoma, the airports at Hutchinson, Kansas, and La Junta, Colorado, Continental Divide Raceway at Castle Rock, Colorado and Mid-America Raceway in Wentzville, Missouri. There were others.
There is an attorney by the name of David A. Tracy in Tulsa. By his biography he is too young to be the driver of this car. But, he may be related to the Dave Tracy who did drive it. You can find David A. Tracy's office address and phone number with Google.
