trans has brass levers w/ball & detent side cover.
The major change for 1971 (actually a late-’70 running change) is a redesign of the side cover and interlock mechanism. New sheet-steel interlock levers replace the old pin-and-balls type. The setup required new internal shift forks, which were now made of cast steel instead of brass. The entire side cover setups can be interchanged either way, which is useful, since the ’70-down type is generally regarded as better for drag racing and serious abuse.
