Note 1: Rain Rail is a molded piece of plastic, it’s not exposed, can only be seen when the top cover is off the top frame.
Note 2: All Miata tops have Rain Rail attached to the bottom of the top under the rear window. Purpose of the R.R. is to keep water going into the trunk of the car.
Note 3: it’s a common practice to transfer existing Rain Rail into new top, unless you have a water issue or the existing R.R. is cracked, then you need to get a new R.R.
