Whatever your 2G is capable of, the 3G will kick it's butt.
There is a big brother to the 95 amp small frame 3-G
It can slide right on in, if the adjustment bracket with the long slot hole can be levered wider to accommodate an extra inch and a half increase in diameter, the swap is a snap. The 130 ampmodel is almost unbelievable at idle compared to a 2G - try ninety to a hundred amps!
The voltage regulator fit, is different between the 2 alternators the 2G ad the 3G. If your rig has a full digital instrument dash the alternator demands a white colored regulator.
The big 130 amp 3-G has a violet color stator that is visible through the holes in the case.
