You might need to bite the bullet and take the boom to a local machine shop. They can fabricate a stainless eye-bolt with the "nail-head" male end to fit the boom receiver device. Should be less than $50.

Try TacKle Shack in Florida, Don's Salvage too - or Minnie's in Newport, CA the part is old school technology so you have a lot of new options to consider.

It was never a roller-reefing boom to my knowledge. Nor is there any evidence of such a set-up, except the key fitting (subject of this thread).
It looks like the t ball parts that West carries are all swage fittings. I'm really hoping to find a piece that looks like an eye-bolt with the t ball fitting (nail head) instead of the threads, if such a thing exists. Then I could simple fit it to the slot and attach the snap shackle from my vang.

Exactly what we had on a former boat.. the top block for the vang had that 'nail head' fitting that slotted into that keyhole.. as long as the vang had some tension it stayed put.
Is this an originally roller-reefing boom set up?

Thanks for the tip 75R20!
FYI - Here's a picture of what I'm referring to:

Depending on the size of your boat/boom, the key slot that you describe is made for a rigging fitting that is usually used on the upper end of a mast,on a shroud/stay. Check with a rigger/sailboat supply for a "T slot fitting " or "T ball" used in a mast. WM lists 3 different styles and several sizes.
Best of luck

After contacting Ronstan and Harken, it looks like the part I may need is called a "vang key". But the funny thing is that they seem to be made almost exclusively for Lasers, so it may not be stout enough for my application. I'll post a picture later today...

One of our former boats had this same fitting - it was a keyhole slot for the vang, the tackle for which was connected via a "nail-head" type of stud that slotted into the fitting.
This was on a boat originally fitted with roller boom reefing... I believe it was to allow the vang to be used for a full main, but quickly removable to facilitate rolling the boom for a reef (but ironically leaving you 'vangless' when you perhaps needed it most)
