so if I buy a GM rotor, 5 on 5.5" , 11" diameter I will have something that fits?

No.
Besides, you’d have a hard time finding a five on 5 1/2 GM rotor.
The hub and rotor are ‘76 to’79 (later too) Ford parts, as mentioned earlier. Only the spindle, backing plate, and calipers are GM.

Go back and re-read post #16 in this thread. I explained there exactly what to buy.

got it, thank you!
So after searching for that era of Ford replacement, there is very little (to none) that are drilled and slotted. I always do drilled in slotted, as I am in Colorado so going up and down is what our roads do. I am still thinking there is much broader range of replacement parts.

Although I don’t have any myself, I wasn’t aware of any problems finding drilled and slotted rotors for our trucks.
I would think a couple of the big names have them. Of course Wilwood does, I bet, but I think they’re more specialized and expensive than necessary if all you want is a plain old drilled and slotted rotor.
Seems like StopTech/PowerStop would have something.
Or you can always check Wilwood. I guess I’ll have to look at our own stock and see if we carry one that’s just a replacement rotor, and doesn’t require anything special to make it work.
We sell plenty of full kits, of course, but I can’t remember the details about just the rotors.

A plain rotor will be better than a drilled/slotted rotor for your application because it will have more mass/metal and therefore a slight increase in thermal capacity - good for those Colorado mountains and passes!

I was just reading an article about how the drilled/slotted rotors is now only a fashion statement. While it did have a reason for existing when first done, pads were very gassy in racing conditions and the vents would let the gas out so the pad could contact the rotor. Downside is there is less contact area since friction surface on the rotor has been deleted. Modern pads don't have the gassing issues of old pads.

I’m OK with a fashion statement.
Especially since most of my rigs are using 20-year-old pads!
