Guys
I bought one of the painted gas caps assemblies to increase the bling factor on my Gen V and I have reached a point of frustration on the install. I have been able to remove 3 of 4 of the retain fasteners behind the assembly that keep the external parts attached to the internal plastic bezel. I cannot find any tool that effectively can get at the 3/8" nut that holds on the fourth fastener which is at the 10 o'clock position. That nut is opposite of the access area in the rear wheel well and I can't get to it with the smallest of sockets.

Also, does anyone know what I do when (if) I get that one off? Seems to me I have to pry off the rubber gasket/surround on the outside of the fill tube in order to pull out the OEM cap and surround?

If anyone has experience here, I sure could use it before I continue to throw tools around my garage.

Thanks
