I know on the A body cars I've seen black painted centre links and natural (bare) tie rods with painted tie rod sleeves.
I'm not sure on the X body cars. Also, the next thing may be that even if you go online and check Novas to see what is correct, the info will likely be American and the Oshawa cars may well be different.
