Been thinking about buying one for a while, would love to know why they changed it (cost, function, shortage)?
Function would mean removing a bushing when getting old stock from a dealer.
Cost would mean I would ask for an extra bushing.
Supply shortage would mean for me to think even longer until it gets better.
Edit: I can think of a fourth possibility, installation error with the center bushing and resulting customer complaints (=> I would ask for an extra bushing.)
