I found a car at an affordable price. How do I tell if it is a real 442?

I purchased it for $1000. It needs a couple of trim pieces such as the scoops and the pieces from the wheel opening to the front bumper on both sides. Does anyone have these items for sale? What can I expect to pay for these?

 

Expect to pay dearly for pot metal especialy the 1965 only 442 side gills.
