NS: 9. Walker (see 0:14 & BL). In the starting lineup I could verify all numbers but 18 Hope & 5. Adams, but as stated earlier, Norths players appear to keep the same jersey number all year in 1975. I couldn't see the replacement numbers.
Parra: 14. Gerard (see 0:22). In the starting lineup, I could verify 1,2,5,7,8,9 & 11. This leaves numbers for McMartin, Cheney, Webb & Charlton who were all late changes to the announced lineup. I could see the following numbers in the clip - 16 @ 22 sec, 17 @ 29 sec, 15 @ 40 sec & 20 @ 46 sec, though who is who someone else would be better placed to decide.
