Hey guys, I have a standard pole sign with porcelain globe holder on top. I am trying to remove the globe holder as step 1 of disassembly to restore sign. It obviously hasn't been apart for a LONG time so everything is rusted in. I have the small screws that come in from the top removed (twisted off) but have only been able to remove one of the four long bolts that appear to hold the globe in place but also pass through the 3 pieces of the globe holder. My other three are just spinning now as it appears the nuts inside have come loose from whatever held them in place. Any advice or pics on getting this apart would be very much appreciated. Thank you for any guidance in advance!
