Small Case 3G

  • Sponsors (?)


'95 Mustang Cobra. I've got the 3g small case on my '73, it fits perfectly where the old 60amp small case went.:stick: By far, one of the best things I've done to my car. It used to charge 12.8 with A/C and headlights on with the old alt., and went to 14.35 with everything on with the new one.:banana: :banana:

Thank you, are yous sure you got the small case 3g off of a 95 cobra? My 94 cobra has a large case, and the part number crossreferances to a 95 cobra as well.

do you know other vehicles a small case 3g or 6g might be on (like ones I could find in a junkyard)?

thanks
 
I have the smaller case 3g, no cutting required. It is from like a 92 Ford Econoline V8 95 amp. The vans with a/c had 130 amp alternators, so go with the no a/c option if going to a parts store. Its not as good as a 130, but its better than stock crap.
 
Hey, just looked at Napa online, and found that a 1992 Aerostar suposidly come with a 60, 65, 70, 80, or 95 amp alt with both the 3 and 4L engine. You guys have a good methoud for visualy telling the diffrence at the junkyard?

thanks
 
Wish i could help with that one. If you go to some of the auto parts websites, I am thinking Advance Auto Parts. They will show you what models it is all used on. But to look at the outside of it and know. I don't know of the answer to that. Hope someone else can help you with this one.
 
I believe this is right, i think it is the small case.
