Front brake rotor size???

[ellisjay2]

There are three different size rotors, I was just wanting to know what size mine were on the 86 2500 longbed, before I stopped by parts store and go through trouble to find out, I can take wheel off and just old school measure it but was tring not too for now. I just read a post someone posted with specs on body and parts that showed 11inch rotors for heavy duty model. I 've been tring o find a site that has all original specs on the whole truck front to back, chassis and all. Then I found a set of rotors for $89 bucks a piece!!! Un! Im gonna shop around to see if I can beat that online probably be best.
