Wow I honestly couldn’t tell you that. It’s been quite awhile now though. Pretty sure keystone was still an NHRA track at the time.

When did they change the tree from 5 yellows to 3?

Prior to year 2000. If I remember correctly, when I took a break from racing about 1985 it was still 5 bulbs. When I started racing again in 2000 it was 3 bulbs.
