Our 43G &
63G series PROPOWER alternators feature a new hybrid
design that takes advantage of the best features of several different
models. Designed specifically for Ford and many Imported vehicles.
Their relatively small size affords a lot of power in this compact
package. Easy bolt-on and simple plug in. The regulator is built in so
there is nothing else to mount. Easy installation instructions are
included PLUS all cables and Alternator connectors are labeled.
(Adapter plugs and brackets required on some vehicles.) The 63G series may
not fit your particular vehicle as it is larger, call for details. If
you have any questions please send Email to: Dennis@mechman.com or call (760)
244-2049.
