... but the tabs on the internal slider plate that pulls the bolt back.
I ordered one of John's handles - a work of art... but it is the wrong dimensions for my 1988 Excella. I also ordered the entire mechanism with filler plates just in case.
While stressing over whether or not to bite the bullet and do the new lock mod I took apart the original lock and determined that the protuding tangs on the door handle were OK, they simply had nothing to make contact and pull the bolt back.
See picture... obviously the metal tabs are gone. Look to either side of the oval hole in the middle. The irregularities in the squarish holes are evidence something was there.
I would have had my neighborhood "metal magician" weld on new tabs but he was off in the Baja racing his buggy so I had to get creative, at least temporarily.
Just above the square holes is barely enough room to put replacement tabs of sorts. I could have used some small angle brackets, but opted for a pair of 1/4" hex standoffs.
I removed the plate, drilled and countersunk (on the back side) holes for flathead 6-32 screws. Mounted the standoffs of the front side - tah-dah! Good as new.
Apparently I do not have pics of the disassembly, drilling, etc. but a pic of the final result as seen from the handle-view.
I hope, if you can get it all apart, you can figure out what I did.
Replacement plates may not be too difficult to make - if you can find someone will to take the time to probably laser or water-jet cut all the holes, etc. but I think welding on a new stainless tab may be cheaper, quicker and easier.
This does not help the possibility that my handle will eventually break
