Chris (Evil Bob) makes the screens and provides the fitting plates but you will still need the Triumph mount collars that fit to the forks (same as with OEM stuff)...these:

An example screen on my bike (as per my avatar), I prefer it to the OEM as it's wider, makes the bike look a little meaner and gives ample space behind for a sat nav mounted via ram mount
Chances are he'd be happy to paint and laquer the screen at an additional cost if you could agree of a suitable paint...alternatively you could go with a more "sculpted" design to get away from a colour matching need...
