Is it possible to use a 98 GT alternator on a 99 GT
Is it possible to install a 98 GT alternator on a 99 GT? All the heavy duty high heat resistant/high output alternators are made for 98 and earlier Mustangs or 05 and up. All the 99-04 "high" output alternators are pretty much the same using the same materials as the OEM one and aren't that much stronger. My engine creates a lot of heat especially in the TX heat (sometimes 110+ degrees) and these so-called 99-04 PA performance alternators are pretty garbage under a full load of 3000 watts worth of music, lights, and a/c. We all know alternators suck in the heat but I see some really high speed made ones for about 600 bucks that claim to output 250-300 amps and resist high temps. Unfortunately they're made for every Ford vehicle but the 99-04 mustang...
