Speaking of the triple monitor mount, I noticed silver-tone brackets versus the black plates on the chassis.
Did you opt for raw aluminum in what appears to be a beaded/blasted finish vs. powder coated steel because these items are typically far more likely to be adjusted than steering wheel and seat uprights?
due to covid my favorite powder coater went out of business. i tried sourcing a good powder coater but no luck. with the current power coating prices i found this would add an additional 200-300 to the prices i gave you so i just stuck with blasted.
