Sorry to hear about the scoot and glad the brother in law is ok. I have two stock shields here one is cut down a few inches and the other is factory hight. You can have either one . I think I have a few of the brackets from the left side that go under the fairing. Let me know if you need any of them.
I usualy get most of my parts from Partshark.com. Have an order coming in from them now. Front brakes are one of the items I am getting. I will order another set and have them on hand.
I have the Back-off modulator and have had it for five or six years. I have it hooked to all my brake lights. Two on the saddlebags, the under the trunk and the brake light. Have not had a problem yet and hope I don't.
I am putting a new set of E III on before my trip next month. And I run the 130 on the front, have used them the last five years. Can't see any reason to change brands now.
I have used acetone for 36 years at work. Have brought a lot of it home. Store it in Pepsi bottles with no problem and mix it in a spray bottle a little at a time.
When I wired mine I came off the relay with a spliter wire and ran them to both horns. When I put the trumpet horns on I used another relay for that set. When I installed the electric horns under the fairing I ran another relay and used the horn wires from the lower left fairing to activate them.
David your horn will set just behind the floorboard. Here is a pic of mine.

Yes you do have to remove the original brake arm to use the Barons lowering kit. To put it back to stock height you will need the stock dog bones and brake arm.
It is the hotdog loohing thing at the bottom of the jugs between the sylinders.

Glad you did not hit the tractor, that would have been bad to say the least. I have always let off on the crest of a hill or a blind turn for just that reason. You never know what may be in the road.
