The Quadratec 63 Amp Alternator is a direct fit replacement for the Jeep CJ, Wrangler and truck bodies. This power plant installs in place of the original using the factory 151 connector, so no splicing is necessary, and featuring mounting for both metric and standard applications. Other factory alternators were 56, 66, 70, 78, 85 and 106, whereas this will fit the location, power output may not be the same and some accessories may be affected like winches and lighting. Please evaluate your electrical requirements prior to changing amp output.
