how are the threads on the brass coupling ?? shot ?
Run a tap through it to see if they will clean up.
I just put a thread gauge on the one I have and it is indeed 1/4-28 x 1" .
I got a couple of NOS off of ebay.
I am "assuming" that if you tap it out to a 1/4-20 and use a good thread lock, it is ok.
(that is probably what I would do if it were mine and did not have a spare).
