Yep, there it is. Press the studs out and you'll soon find out that the rotor seperates from the hub. I can see the parting line in the pics even.

Missed this post sorry but this almost answers my question.
I know the rotors slip over the studs on the front. so I would think the stud holes in the rotor are slightly larger than the threaded part of the stud. The studs are bigger where they go through the drum. So Im curious if I will have to bore the holes in the rotor so the studs will go through. I guess I will see when the parts get here.
Wrong again, the rotors mount to the back side of the hub and the wheel studs go through the rotor and then press into the hub to hold the rotors to the hub.
Yea it doesnt really matter I have new ones on the way that dont have grooves worn into them.
Maybe I am wrong but I just do not see where they would come appart.
the hub steps up for the rim to ride on then curves right into the rotor there is no separation.
Do you mean like the rear drums?
AHHH hell man Im sorry I see it now. In the pic below. But you could have told me that rather than telling me I need a 4wd and what I have is a 2wd. It would have saved a lot of arguing. The implication that I was dealing with a 2wd rotor is what set me off. So once again I am sorry.

To be honest I usually dont have time to do brakes myself and usually pay big O to do them. I know the rotors just slide right off on 88+ trucks, I was under the impression the earlier rotors did as well.
Anyway you can kinda see the 1 bad groove in that rotor and the inside has worse grooves. So the new rotors are going to be better anyway.
Five hours ago you were very adamant that yours were one piece, now "maybe you're wrong". Which is it?

I would like to see a pic. There is no such thing as a 4WD with a one piece hub and rotor

Yep water off a ducks back its no big deal since I got the answers I was looking for.
Now I need another answer though are all 73-87 front rotors pinned on with the studs? or just 8 lug? or certain year and newer?
One of the reasons I have always let big O do my brakes is so they could turn the rotors if they needed it. The only vehicle I have ever had to replace a rotor on was my 97 1500 when I first got it the driver side rotor was worn clear into the center vent portion. The outside brake surface of the rotor was ok but the inside surface was gone. I also had to replace the caliper as it was messed up as well.
The earlier 14b were pressed on 73-83?
83 and later were slip fit?
Ok these 2 answer the main question and since nobody has ever said anything about boring the holes in the rotor I assume they fit.
just to be on the safe side I ordered rotors and calipers for a 1975 gmc 3/4 ton 4x4. Did I order the right ones?![]()
Hmmm never seen a drum pressed on but then again my 14b is a custom frankenstein.
Could someone throw up a couple more pictures of pressed on drums just so when i do have to deal with them I'm not scratching my head.
