Not a Crossbones, but my PCIII would not fit under the Mustang seat on my FXSTI. I ended up velcroing it to the front of the mudflap. It is very secure there on it's own and the velcro becomes more of an added security measure than anything else. I will try to get pics for you if I have a moment before work.
Hope this helps.
Thanks...pics are always worth a thousand words. Jamie at FuelMoto suggested removing the relay tray and mount it also on the mud flap, but pics would be great. Jerry
I do not have a PCIII, but I do have a V&H fuel pack on my Xbones. I mounted mine on top of the battery. You will need to trim the ribs off of the bottom inside of the plastic seat pan, then it will fit. I dont have any pics right now or I would post them up.
I have a TMax... but I have read where you have to grind the ridges from the bottom of the plastic frame cover for clearance... go to the Vance & Hines Fuel pack website and look at the installation instructions for the XB....
Thanks for the suggestions. I would assume that the FuelPak and the PCIII are similar in size, so mounting the PCIII on the battery may be a good option. I will check in on that. As for mounting it in my toolchest as Aggro Jo has done, I will pass...cute
