Thanks time for the torch to melt the powder coat.Yes, It is just crude up.
No way WD 40 would loosen that up it was covered in powder coating not even a crack. The powder coating was smoking before it came loose it's a reproduction part, so nothing harmed. I tried PB Blaster before the torch would not budge.Why not anchor the mounting bracket in a vice, spray the pivot joint with WD40 and work the arm until it loosens up. Beats ruining the powder coating with heat.
