Here is what you need to tell AZ or O'Reilly:

1985 Chevrolet C20 (3/4 Ton), 2wd, 5.7 engine
Front Calipers for Heavy Duty brake system, 13" rear drums

For reference:
Front Right Caliper is a ACDELCO #18FR649
Front Left Caliper is a ACDELCO #18FR650

These require the 10mm banjo bolt and hose

Ask for the front hoses for a 1985 C10 with the heavy duty brakes.
