Thank you so much Ronnie by the notice and the photos too.
As I don't know of any existing engine near me not always it is clear, my support it is photos that I found in my searches or some help from the members of the forum.
Now i believe that is correct, the left that i have, the right it is the new one.
The engine that I have been designed it is the 59AB.
Thank you all for the help
All the best,
Jorge
