Re: 1'' Rotors And Calipers
Why not buy from a local parts store? Then you can check them out before you pay for them.

Re: 1'' Rotors And Calipers
I'm pretty sure 73-80 is a 1.25" rotor and 81-87 is a 1" rotor

Re: 1'' Rotors And Calipers
Yep,... 81-87 trucks could have either rotor width.
Usually the 1" rotor trucks have only 2" wide rear brake drums. That's how my local parts house shows them.

Re: 1'' Rotors And Calipers
Here are a couple brake system release charts (for a '74, and for an '87).
http://67-72chevytrucks.com/vboard/s...d.php?t=510519 This will give you an idea of where the 1" rotor was used. Typically it was the lightest of the light duty trucks (GVW wise). K
