That's what I thought, but I got some stock firebird pads and they are not the same.
I'll get some Eldorado pads and see what they look like.
If you asked for brake pads for a 68 Firebird they won't be the same, in 69 they changed to the single piston caliper, if you order pads for a 69 Firebird they should work, as most GM cars used the same pad through the late 70's maybe even longer. The pad number should be D-52, there can be more letters for the different type of pad material, Don't forget to get new rotors or at least have those turned
