UPDATE
The CEO of Oakridge BBQ (see above) got back to me and said he's searching for the contact info of the person who made their custom 26" griddle. He's confident that he'll find it and will send me the info.
More to come......
UPDATE
The CEO of Oakridge found the contact info, sent it to me, and I reached out yesterday. This morning, his wife replied and said he passed away. Definitely not what I was expecting, but I was simply amazed that she took the time to respond and so quickly. I'm not sure when he passed, but his wife was super nice and said her sons could make one for me over the winter (they live in Florida). I told her I didn't want to bother her or her family under such circumstances, but I left the door open to seeing what they'd like to do when winter comes.
Anyway, that's the latest - I'll let everyone know what happens next!
