Rear disc brake upgrades recieved

[new to this]

I just recieved my rear disc brake upgrades today from ebay's tomsclassics and everything is there but i emailed the guy and asked about replacement parts for when the pads and rotors will need to be replaced and i have not gotten a responce yet. I took a look at the brake rotors and found a part number of 5568 and as i checked i think that part number is a good part number for my local auotzone . I found the part number on there website and i think the brake pad are the same as the seville pads because the brake calipers look just like the seville calipers. The reson i picked this converson kit is because it is with in my price range and the other reson is the rotors look like they where made just for the six lug bolt pattern, not rotors that had the holes welded up and redrilled.What i was wanting to know is if any one has fould any brake rotors that fit the 6 lug bolt pattern. I have attached some pictures of the conversion kit.This kit was $399.00
