brake rotor ?

[MalibuSSwagon]

I just swapped over to 1.25 rotors on my C10 (along with the drop spindles) the cross reference on calipers for my truck went back to 1979. Looking on Rockauto for calipers and rotors, it is very confusing when trying to pick out the correct big rotors and calipers for a 81+ C10.

So, when I went to my local O'Reillys, because shipping is insane on these heavy pieces, I asked for rotors and calipers for a 1979 C10, since 1.25 was the only option that year, the parts jockey can't screw it up. The brake lines will bolt up.

Yes, there are different calipers for each size rotors, the 1.25 calipers are .25 inches wider than the 1.00 calipers. Weird right? haha. You'll know if you have the wrong calipers because you'll load up the brake pads and they won't fit over the rotor.
