REME Help required

[Dan Sicotte]

Yes, sorry, I had a couple of little boys distracting me while I was typing.
The inner tracta joint on the right front is where the problem lies. I hear no noise while I drive, so it's not touching anything important....as if I could hear it anyway.
The obstruction has a 1/4 inch by 3/8 inch slot that seems to be a reciever for a male ended tool. I can't see the top end of the threads, so I think it's screwed in, but it's on there really tight. I tooled a piece of flatbar to try and remove it but it was no good....the flatbar is too soft, and it just rounds out of the slot.
I was thinking of drilling a 1/4 inch hole in it, to allow the fluids to drain. But I wanted to make sure with you REME types that it wasn't an emer Modification. Afterall, I am an ex-tanker.....Make it work!

Does the inner bevel box vertical plug look anything like this?
Thanks for your time.
