Now this might not seem like a lot but it makes the world of a difference.
The tour pack brackets are made out of aluminum that mount to the factory tour pack locations. Then the tour pack mounts onto the brackets
The second set of tapped holes is to move it back another 1" if you want (2" total)
Now adding the bracket does move your tour pack up the thickness of the bracket but it isnt noticable when looking at the bike unless you look under the tour pack itself.
Now to move the seat back we made a tounge extentsion out of aluminum. Unfortunately i forgot to take a picture of it but the factory tounge that the seat slips into has a hole in the middle of it from the factory. We took a piece of aluminum again milled it down to size and just drilled and tapped a hole to bolt onto the existing tounge. For the rear mount on the seat it bolts into the fender. We had to drill a new hole 1" back from that hole and put in new threads
There was no cutting or altering of the original seat it moved back without any issues.
