Feed throat$ are like hen$ teeth. Not impossible to find, but be prepared to $pend a bit.

 

Good luck with your search. I bought the only two sets I could find about a year ago. I haven’t seen any since then.

 

I'd suggest you look at threads regarding 're-building' the old throat assy. Unless it's really 'severely worn out' you may be able to salvage it by judicious drilling and screw/bolt-ing the halves together, or using epoxy to bond them ? As said above, the likelihood of finding replacement parts is diminishing. Looking and watching fleabay is your best hope . . .

The new style can be modified. Look at Arrowdodger's vidio.

 

I haven't seen any feedblocks in a while. I ended up buying a new style sidepalte assy and doing the above modification. One of my older model 60s had the built in ejector and it was worn to the point of constantly stove piping.

The new block with the wire has worked flawlessly.

Upsdie to buying a sideplate you get all the parts for the swap plus spares.
