Fred Lagno holds the STC for the 60 amp alternator. He sent me the wiring digram and installation instructions before I bought the STC. He was very helpful and the STC was $85.00 (several years ago). I did the installation in my 120 and was very happy with the results. This letter is from Fred from a previous post......

ALTERNATOR INSTALLATION INFO, ALL AIRCRAFT
Our installation utilizes a Ford/Cessna 60 amp alternator that bolts directly onto the C-85, C-90, O-200 and O-300 engines. The installation is a standard alternator circuit providing a nominal 14 volts for aircraft with 12 volt battery systems.
The following parts would be required:
Alternator
Voltage regulator
60 amp ammeter
Voltmeter (panel-mounted). Our STC lists a combination gauge that allows a constant ammeter/voltmeter readout. (Not required for Cessna 120/140/140A).
circuit breakers
noise filter
other minor parts for alternator drive and blast tube assembly
We provide the Supplemental Type Certificate, full instructions and schematics, and a list of suppliers for parts. We do not provide parts for Aircoupe or Cessna 170. However, we do stock the VR600A voltage regulator for the Cessna 120/140/140A. As of this date we are the only supplier for that part. A rough estimate of parts cost is $800 to $1000.
Aircoupe and Cessna 170 owners: to order, please send a check or money order for $85.00 and include aircraft type, registration number and serial number.
Cessna 120/140/140A owners: to order, please send a check or money order for $204.00. This cost covers STC, voltage regulator, and shipping. In addition, I will need your aircraft type, registration number and serial number.
I am certain that you will be pleased with the dependability and performance of this installation. It is one that has been used for many years, and continues to be quite popular in small aircraft. If you have any further questions, please call us.
Sincerely,
Fred Lagno
