unable to find the front brake rotors,have they been changed to a different styl

its a 4x4,454 eng.,manual tranny,gvw 6ooo lbs I looked at the one from napa,everything looks good,except mine doesn't have a bearing. its held on by a big nut.thats why I thought maybe it had been changed to another style ,due to a change.

Ok, I gotcha now .. The brake rotor and the hub bearing seperate from each other and then it becomes a two piece assembly .. The following are NAPA part numbers: IF you just want the brake rotor, this is the part number to look at > Brake Rotor - PART # > UP 86242CR > K2500 GMC Pickup Now IF you need the hub bearing as well, this is the part number to look at > PART #BRG BR930406 > K2500 GMC Pickup The part numbers I posted are for reference only! .. You still need to be sure the parts people get 'ALL' the information you posted here, especially 4x4 & GVW.. This link is to a YouTube video showing how to replace the front brake rotors: https://youtu.be/o1YvvmUALfo Merry Christmas!
