This is a 45-50A Alternator for Mitsubishi Built Trucks. The Same Thing, in a 65A Version, is the 14428. For 75A, Use the 14438. The Two Numbers Listed are Similar Enough to Supersede Each Other. The Same Unit, But With a Slightly Offset Top Mounting Ear, is the 14430. The 14430 and 14432 Interchange, if Desired.
