Default LS1 and C5 rotor size?

Hey Guys
I have a question for you.I am changing my current G body brakes to a Ls1 12 rotor size .There is a company that makes a centre hub for my spindles but it is for the C5 corvet brakes and comes in a 13 inch rotor.I was wondering if there is a size differance in the hole size of the rotor between the two and also in hight( if you were to lay both rotors flat with the hub facing up)
I would call a dealership now but they are closed .I was hoping to order the hubs online tonight.
Thanks Again the LS1 site rocks!

Any web site that might help me with measurements on the two rotors? The GM dealerships has to order the brake rotors in(I find that strange)
Thanks
Mike

That is a really good question, hopefully some one here that has done the swap will have an answer for you.

The center holes are the same
LS1 is 11.9 OD with 3/4'' offset
C5 is 12.8 OD with 1/2'' offset
offset is from rotor face to hub face
