Question on BCD parts terminology, and repair......

[Mark IV]

(edited) Here's the situation: I just got an ebay deal on a very clean, older, and complete Sherwood regulator set-up (I loves me some Sherwoods), that also came with a basic, rental grade BCD. The reg, which is what I was primarilly interested in, looks fantastic (at first glance), but the BCD is all jacked-up.
This is an older (also very clean ) Pro-Sub vest, but part of the assembly on the inflator hose, the "elbow valve" that attaches to the left shoulder, is busted up, and needs replacement.
(as I understand, Pro-Sub has been out of production for over 10 years, but i'm hoping this common part is available somewhere).
Also, the hole that it threads onto on the BCD, appears to have a smaller than typical diameter, it looks to be only 1" (outside thread to outside thread).
I seem to recall most BCD's usually having a much larger hole, so if there's a "universal" BCD replacement part, they may not fit here.
Any advice, info, links, points in the right direction, etc. would be highly appreciated !!

probably best to take it off, post some pictures and start there.

sounds like you need one of these, but that is the "Standard" inflator assembly.

inflator hose elbow. Maybe check DRIS or LeisurePro for oddball sized ones.

yep, thanks guys, i was just about to post that I'd found out it's the elbow valve. I'm seeing a couple replacements, that are even pretty cheap, but the ring diameter is too large.
edit: I'd already checked several of the usual suspects, but no joy. I think it was DRIS that had one made by Dive-Rite, for only $9, but the dialeter is 1.75". That's probably the same unit that's part of the full hose assmebly recommnded above by tbone.
