Thanks for posting the great before and after pics. I've been debating adding the layflat bracket for sometime along with the key relocation. Now I just need the $ and time to finish up with other mods to the bike.
D9 has a Vendor area dedicated to his brackets. Look towards the bottom of the forum in the Vendor area. You should contact D9 in his Vendor area or directly thru the forum's PM feature for pricing. He has many different brackets to choose from.
