For anyone still getting updates about this thread, I'm looking to buy or borrow your underneath bracket so I can fabricate my own. I have this IC on my 09 FXT but it's missing the underneath bracket and it costs and arm and a leg to get one from an Australian vendor.
If you have it and willing to let me borrow it, please let me know. I am willing to pay as well as offer some car parts I have. Check out my iTrader feedback for my rep.
