Table schema:
CREATE TABLE table_name_92 (position VARCHAR, test_debut VARCHAR, year VARCHAR, cross_code_debut VARCHAR)

Question: What is the position earlier than 1907, with a cross-code debut of inaugural rl test v new zealand, and a test debut of inaugural ru test v new zealand?
SQL: SELECT position FROM table_name_92 WHERE year < 1907 AND cross_code_debut = "inaugural rl test v new zealand" AND test_debut = "inaugural ru test v new zealand"
