Its my understanding the 1 ton calipers are the same 7" pin spacing, except larger bore and wider throat - for the 1.50" thick rotor vs. 3/4 ton 1.25" thick rotor.

As long as you keep the caliper & rotor paired together, either will bolt onto the C20/C30 spindle.

Folks only use the 77 year as a convenient reference point when sourcing parts from yards or parts stores, since it was the last year of SAE threads before the caliper banjo fitting (among other fasteners), went to metric.
