5W doors are 26 1/2” roadster doors are 24 1/2” cabriolet doors are 27 1/2 . Don’t know if this affects the subrail or not at the B pillar . But will probably go with Newc suggestion , what ever we get we will just have to make fit. you can see why we want to replace the sub rails , 1/4” plate and tacked together parts with great gobs of filler and or silicone sealer . The brown stuff is from me sandblasting the hideous away.
