Is there any type of plug or cap available that I can use on my 1968 transmission? I am not going to use a speedometer as it is race only. Thought that it may be possible to remove the gear from the trans and find a screw on cap.

Why bother. Leaving the gear in doesn't cause any harm and you don't gain anything by removing it.

No info on a screw on cap but Munroes 727 bible states a 1&49/64" freeze plug. On your gram scale (my ten dollar Harbor Freight one works great

) see how many grams you are eliminating going from the alum speedo adapter to a Dorman steel freeze plug

That's what my JW-built 727 came with there.

I found that a International Scout uses a Torqueflight with a threaded cap on the speedo adapter. They run the speedo from the transfer case. Not sure of the years but guessing 70's and 80's binders{IH}
