Supercar Collectibles Sox and Martin cars

I have a set of 1/18th scale diecast Sox and Martin cars made by Ertl for Supercar collectibles. One car is a '67 superstock Hemi Belvedere and the other is a '67 superstock 440 GTX. They were never displayed and are in mint shape. I bought these as a set and selling as a set.

$80.00 and free shipping.
