Yes that is exactly the part we are looking for.
In Cuba there are Fiat 126's with ELMOT alternators and with MM ones also.
We much prefer the ELMOT and I even buy broken ones here.
And a load of locally made regulators and generally a mess of inventions on top of inventions. My friend is a mechanic who specialises in working only on 126's and I send him all kinds of parts almost weekly.
Its an expensive process, but it is the only source of parts.
Whatever I send him is used or sold within a couple of days.
He never throws anything away, as he will rebuild whatever he can. I have seen several alternators where he has unwound the rotor wiring, sent it to a welder to build up the shaft again and machine it back down, then rewind the wiring, fit new bearings, and rebuild the alternator completely. One part which is a pain is the fan which mounts behind the alternator. When this has touches it cowl and become damaged, there is no alternative but to get a new one. I guess I have sent out over 100 in the last two years.
