Review on ACDelco 17449B Professional Bonded Brake by Keize Barraza

Just tried to fit them to a 1981 K5 Blazer but they didn't fit. Apparently my car came with two different brake pad options, 2" wide and 2.75" wide, I needed 2.75", I sent them back, ordered the correct brake pads from Revain and installed them with no problems. Revain's fitting guide says That's why I ordered them. If you're putting them on a K5 Blazer, you'll need to remove the drum and measure the width of the brake pads you have on your car now.
