what rotor with 951 calipers on late ali arms

[boygenius]

My trailing arms have the 951 prefix on their part number so I would assume that they are the same as the turbo. But there is also a 302 prefix number on the trailing arms. I think though that the N/A and turbo arms are the same and that the onlly difference is the caliper and the rotor. I'm not really sure though. Let me know if you need my N/A parts to get you to dyno day.
