Red94Mustang

I have a 1994 Mustang and one of the stems broke off on the EGR tube (the smaller one). These seem to be near impossible to find. Also getting the tube out is extremely difficult due to the lower bolt’s location on the manifold. For now, I put a thread on both ends and screwed the stem back into its spot and also put some JB-Weld Extreme heat to prevent exhaust leaks. It did eliminate the exhaust fume smell in the cabin which is good (every time I turned the vent on when idling). I had to do all of this with the tube in the car, which was difficult.

I have searched for many hours and I am having difficulty finding this part. Is there a site out there that exists other than eBay or fordonlyparts.com (already tried them) that might have parts like this? The part number is F4ZZ-9D477-C. I also tried asking in Facebook, but I am just getting scammers that are taking pictures from Google, claiming that they took the picture. Its very strange that no one has reproduced this part, like there is one for a 2000 Taurus that looks very close.

Thanks!
