3 spd Counter Shafts

A couple years ago when I rebuilt a late 3 speed transmission, I was able to buy countershafts with O-rings on them for better case sealing.

I think at the time they came off of Ebay. Now I can't find them anywhere.

Does anyone know who sells these now?

It is no big deal to machine the grooves yourself.

Well I think for me that would be outside my skillset.

I haven't got a lathe, and i've never tried to cut a groove in case hardened steel.

Last time I bought these I remember them being inexpensive, So given a choice I would just buy a set.

I'm pretty sure the last ones came off ebay of all places, but its been a few years.

I see lots of them available for the model A.

John Kovar has been gone for several years now. If the original poster is determined to have this, I recommend cutting the grooves into an original Ford shaft. I don’t think the aftermarket shafts are sized or heat treated like Ford did. FWIW we don’t do this to any of them, whether it’s installed in a rebuild or sold through our parts business.
 
My transmission was leaking at those shafts. When I installed my flathead I went through the trans. I had the exposed ends of the shafts drilled and tapped for small bolts. Upon assembly I covered the ends of the shafts with RTV and bolted discs on the ends using the threaded holes. I also sealed the locking pin with RTV. No leaks in 6 years.
 
The last early Ford 3 speed transmission that I assembled (50 pu, top loader, w/open drive) the counter shaft had such a neat/tight fit in the case, that I doubt much, if any gear oil will leak out of that area.

* Also, some years ago I purchased a new cluster gear counter shaft and new caged roller bearings for this cluster/counter shaft assembly, and during assembly of these parts in the transmission I determined the shaft and the rollers on the bearings were both undersize. These new parts came from a well known dealer/supplier. I was lucky to catch this problem before final assembly. My point is....check and double check your parts very carefully, whether they are used, new/repro, NOS, or otherwise.

Thanks for the input guys.
I know not everyone uses the seals on the countershafts, but it seemed like an elegant solution to the oil leak problem.
Unfortunately from what Mac VanPelt says, the person who was supplying them is no longer with us.

I do an easy (for me) fix on them, I set up the empty case on the mill, bore the worn bore oversize, then machine a sleeve to fit in the bore, while its still set up on the mill ,I pull the new sleeve in then bore it to size ,to fit the new shaft,
