I asked that exact question among others to SAV today.
To my surprise the answer that I received the second time I asked was exactly opposite of the response I got the first time just a day ago. I am certainly not criticizing anyone, because anyone can make a mistake, anytime.
Here is what I think (key word, think):
The bronze/stainless wear bushing that Bob Rossi received in March 2014 is either an abberation, a prototype, or something that is old. My last email to SAV informed me that the one Rossi received was the "old bushing." Here is the quote:
"" Sorry, my mistake, It is the otherwise. I hadn’t understood your question’s meaning.
On picture you sent, bushing is in steel chrome, it is the old bushing.
Today, it is a new supplier, we have the same one but in bronze. That’s the only difference.
For Amel 64, it is a bronze bushing too but in bigger size.
I hope my explanation are clearer.
Don’t hesitate questioning.
So, I am not 100% sure what is going on.
I will wait for some other people smarter than me to give assurances as to why Bob Rossi received a wear bushing from Amel made of bronze and stainless.

Question: Do you (or anyone else) know whether the old wear-out bearings and their seals can be "mix and matched" with the new wear-out bearing and seals, or are they incompatable in size?
