I can't explain the GPS mounting: I believe it's one of those strange, ritualistic, Ural PFM things. Or maybe velcro.
But, the 4 round black things the individual gauges are mounted in? The owner said he was at the hardware store in the plumbing dept., looking at PVC pipe that he planned to angle cut, paint and then somehow mount up under his fairing, although quite how, he wasn't sure. Upon glancing down the aisle while scratching his head, deep in thought, he said he noticed the old fashioned, $1 toilet tank floats.
"Hmmmm", he thinks, "already round, already black, waterproof, and cheap! If I cut one wrong, it only costs me a buck!"
Four dollars later, some scrap steel bar, and voila, a custom one-off "dash", fit for a Russian King!
