My flap and rudder pedal adjustment handles rubbed against the sides of the console slots and brackets. I got some 1.5" wide UHMW tape from Amazon for the handles to slide against. ( https://smile.amazon.com/dp/B00823J7...AWMR4KP4YDR6QT )
Very tough plastic surface but also very slippery! The handles fit perfectly with no slop or binding.
