Also WorldOfTriumph.com if you're in Europe. They're located in the UK ("Lings motor group").
They have complete parts drawings, you can just go there, choose your bike, choose parts and search.
(I had to buy one of the infill panels myself after I got impatient and forced the left hand one on and cracked it... putting them on or taking them off without unbolting and moving the expansion bottle for the coolant out of the way is **** near impossible on the Touring at least.)
These are in the main frame section. £7.51 each.
