I agree with CAB, band adjustment is not your problem here.

72 inch pounds Is 8 foot pounds, is it not? Tighten the adjuster down snug with one finger until it stops, back off 2 turns and tighten locknut.

1970 manual says 2 turns,
I believe the mid 70's was 21/4 or 21/2 turns on the front band.

Cab, at 3 1/4 turns the band struts might fall out.
