SDR carbon heat shields / part numbers?

I bought R carbon heat shields from ebay but the part numbers are a bit odd, according to the seller part #s are 6110519003149 and 6110519002149. Seller told those are from R and are supposed to be the oem item and to me they look ok but R parts book say numbers are 6110519003049 and 6110519002049.

So the quiz of the day, what did I buy?

(I'm planning to use std exhaust with my R tail conversion so I need R heat shields.)
