How does the 9 bolt rotor with PBR brakes look like?

I have two sets of rotors here and I think one came off a 4th gen rear..One has a taper on between the stud and the hub and the other at a right angle raise.Anybody know which one for the 9 bolt?

 

part two..

Ive been doing the search but cant seem to find specific answers

I have a 9 bolt with PBRs..I found a kit from ebmiller's site but I dunno if he uses the same stock PBR parts..Bottom line is I need to know which parts I can reuse(obviously not the 11.7" rotor) and what other parts to I require(for 13" brakes)

I have a spare LS1 caliper/carrier,C5 rotors and front C5 conversion brackets..

I need to get the rotors turned anyway but if I don have to purchase the calipers then I think its worth moveing to a 13"

 

anybody?

 

well the 4th gen rears have an internal e brake so the the rotor hat is deeper then a 9 bolt rotor. That is if my memory is correct it's been a while since i looked at the 12" 9 bolt setup i have sitting around.
