USAC: 50 Years of Speed & Glory for the years 1984 & 1985 I came up with this info. The only wins listed for those seasons were in a midget, no sprint or silver crown wins.
33 TOTAL WINS
19 Indianapolis Speedrome (1 Indy Midget 500)
4 Fort Wayne Memorial Coliseum
4 Terre Haute Action Track (2 Hut 100's, 2 50 lappers)
1 Eldora Speedway (4 Crown)
1 Hales Corner Speedway
1 Hoosier Dome (inaugural)
1 Kokomo Speedway
1 Phoenix Intl. Raceway
1 St. Charles Speedway
Other than the two 50-lappers at Terre Haute in the Byrd 3, and the Phoenix win in the Wilke 11, all wins were in my dad's midget (74 in 1984, 1s in 1985).
