If it's not too much to ask, can you find the fixture with pigtails online? Is this a fixture with threads so i can trap the dome inbetween them? All i have been able to do is strip the wires back to good insulation and rewire. I can make up a cord with romex and such, but i know the insulation on that wiring doesn't handle heat well. I know the fiberglass insulation you talk about, but i'm curious to see what you've found. Thank you!
