I actually had to use two different setups to get the curved lay down plate i have one was the drag specialties lay down plate for the tombstone light you have to remove the original bracket when you do be careful the bolts come from under the fender and try not to let them drop down they are a little hard to get to. I used the set up from the drag specialties plate then used the kuryakyn curved frame the backing plate on the drag setup is thin and i was able to bend it to contour to the kuryakyn plate frame in all i bought two plate setups to get to the one i have now
