Im not sure. Never heard of one. But when I was in Mexico about 6 years ago I saw a decked out f150 based Lincoln truck almost a year before i saw one up here in wyoming. So it is posible.
But my guess would be that he just put it on himself. Like the other day I saw a Cobra f150. they replaced all of the badges with the snake and even had a strip on the bottom of the truck that said cobra.
Your probably right but the automotive world is slightly different south of the border. Dodge produced a Ramcharger with the 94+ nose that wasn't offered up here and many South American countries would buy up the previous model year production machinery for domestic production.
