I just got a price from my dealer. The cowl kit is $262.49 Add the radiator screen....$106.20. Add the small rear side screens (2 ) in black..$ $250.10.
So..all blacked out = $610.08 for parts alone before taxes.
I think I'm going to go with the look of the new Roadster which is to keep the chrome cowl, change the radiator and side screens to black. Not a question of money but I saw one like this on the showroom floor and I like the look even better than all blacked out. Cost of that would be about $360.
Hope this helps, Mike
