OK, I fess up, I'm a jack-ass! When I checked the bulbs to see if an element was blown I didn't notice that it was. The first time around I didn't take them out of the socket, they "looked good." Well, after tinkering with things front, and rear and underneath, I ultimately had to check the bulbs again. This time I took them out and sure enough, both bulbs lower element were blown. I feel like an idiot now. Nice to have all my lights working again though!
