It gets more expensive when you include disc/drum master cylinder (if you’re doing that)...new plumbing (if needed)...Proportioning valve....check valves....Wheels? (Most kits may not clear stock wheels)…tapered wheel bearings (optional but recommended by some)...Caliper Bracket...New king pins while your at it....
Paperwork I have states the P.O.L. I purchased back in 2009
"THIS KIT USES: 1971-86 CHEVROLET K- 5/10 BLAZER 4WD ROTORS AND 1971-87 CHEVROLET C-10 TRUCK 2WD (HEAVY) CALIPERS."
Of course only use above as reference. Not confirmed or verified
Good Luck
