I have to replace mine too. You can still get the bronze bushing and pin/spring from Alexandria Aircraft. It appears that the same one is used on all the taildragger 14 series. I ordered one a few weeks ago and they are having some new ones made. I called this morning and Randy is checking on the order with his machinist.
Having replaced this once before (and screwing it up - thus the re-order) I recommend installing the bushing without the tailwheel shaft in place. There are three bolts that hold the bushing in place. One faces forward and I found it nearly impossible to access with the fabric in place. I had to cut the fabric enough to get a right-angle screwdriver in there.
I also found that the bolt holes in the new bushing didn't quite line up perfectly with the holes in the aluminum housing. Tried different positions but nothing worked. I got them close and tightened down the bolts as best I could. I found if I tightened too much, it distorted the bushing enough to inhibit free swivelling of the tailwheel shaft so I had to back off a bit. If this proves to be the case again, I plan to mark the actual locations and then drill and tap new holes in the new bushing.
Also, I had to clean up the shaft with emery cloth to get it to slide into the new bushing.
Good luck,
Tim
