Yes, correct part numbers
BUT you still need the chrome TT straps and bolts either 3 or 5 bolt.
The straps
are not and never were sold separately by Triumph and only sold as part of the 'Screen Assembly', either:
Classic / Roadster screen only with straps A9740049
Complete kit Classic/ ROADSTER SCREEN A9748036 Requires Front End Fixing Kit A9738051
Summer screen only with straps A9740048
Complete kit SUMMER SCREEN A9748040 Requires Front End Fixing Kit A9738051
The Triumph Parts diagrams are wrong on some items, but the part numbers are still correct. The image used for the 5 bolt Roadster screen is actually the Summer 3 bolt screen and this mistake is repeated worldwide in Triumph parts listings.
Clearview does both 3 and 5 bolt screens for Triumph Rockets on request.
