IH444 Auxiliary Hydraulic Tapping Plug

Hey all. I'm working on correcting some plumbing issues with the hydraulics on my 444. The Auxiliary Tapping Port on the Hydraulic Control Head is missing the Plug (P/N: 706027R1) and the associated Seal (704337R1). While the seal is readily available, I'm coming empty-handed for the plug, other than it is not in production. Does anyone happen to know the size and thread pitch for this port? I'm guessing that it's not NPT due to the seal, but pipe which was inserted there did look to have a taper, if I recall correctly. See items #1 & #2 in the picture;

Thanks, guys. I tried the Search, and found a mention of it on a 384 thread stating that a 384 plug might be 1/2 NPT, but the parts diagram for that tractor has a description of 1/2 BPT, so completely different animal. Hopefully, it will be something I can get locally that will work.
 
I just went up back and took the plug out of my B414. It is 15/16 hex with 5/8 NF thread, but it is drilled out inside to 13/32 for a
tubular screen about 3 inches long. I'll try to send you a pic. If you cant find something local I will sell this one as I am junking the
B414.
 
Phil,

Thank you so much to you and everyone who responded to this thread! In order to save you further grief on my behalf, I'll see what I can find locally, and get back to you tomorrow. I really appreciate the help.
 
Phil, sorry for the delay in getting back to you. Things got a little sideways here the past few days. I went and got a 5/8" bolt, but I think that maybe the one you have in the pic is for the screen, as you had mentioned previously. The plug I'm looking for is the one where the pipe is coming out of in the pic below. I appears to be a larger diameter than 5/8;
