Here's an update with great results: during the course of my research (including this post), I placed an order with TouchUpDirect (
https://touchupdirect.com/) for my Antimatter Blue and Ford J7 for the fender flares.
When the J7 didn't quite match, I contacted them and received a response, offering to find a better match if they could locate a GEN 3 to inspect. That finally happened, and I subsequently received two tubes for the fender flares and bumper. Both were excellent matches!
Thanks Uri and TouchUpDirect!!
