First of all, welcome to the site!
Is your car Bahama blue by any chance?
I suspect that Alpine blue was VW's way of describing the blue running board, but was never a paint code as it wasn't available as a car colour. Your best bet is to find someone with Alpline blue running boards and get a paint mixed to that.
Probably the same for the interior too?
