Guys, I'm ashamed to admit this,

but while attempting to change out the stock steering head/triple tree for a chromed HD version, I cannot get the chrome cover off of the center nut. I was told not to attempt to pry it off as it is threaded into the top of the assembly and would ruin the cover. It's a 1996 Dyna Lowrider. Very little of the cover is above the surface level of the steering head to get a grip on. It's partially recessed. I tried putting a strip of leather around it and using Channel-lock pliers to try and turn it, used penetrating oil, and tapped on it with a dead blow hammer to no avail.
I made sure it didn't have a set screw somewhere on it that I could simply loosen. The only things I haven't tried that I can think of are either applying a bit of heat, and as a last resort, prying the dang thing off with a pair of flat tip screwdrivers or something! I hope it's something simple , but I'm getting the feeling that the thing must've been put on with Loctite.....PLEASE HELP ME!!!!
