Does anyone know if this part is available anywhere? Its off one of the flappers in my heater. I might try the GM dealer when I get to town, but I'm guessing its fab time.

I used two small metal "L" brackets, one above and below the plastic piece. Screwed them to the metal flap door and drilled a hole to put the cotter pin through all three pieces. I hope this makes sense cause I don't have any pics!
