Georg,
I don't have any pictures as the plate is hidden behind the fork guard part of the Suzuki fender. It has been some time since I made the adapter plates, but I do recall that I made them from 1/2" thick black plastic plate, (called Nylatron here). I simply countersunk the bolts in the original locations on the plate so the heads are below the outside edge of the adapter plates. I then drilled and tapped the plate with holes that aligned with the Suzuki bolt pattern. I do remember that the bolt holes are very close to the Triumph holes on the two bolts on the front. The single rear bolt on the rear on each side requires you to trim about 1/2" off of the boss on the fork lower, no other modification is required for the rear bolt.
Hope this helps, if I get a chance I'll try to get a pic, but the bike is pretty packed in for winter right now.
Lonnie
