The Camper and Trailer Specials had a larger amp alt that was part of the package. Was this a Large Case 1G?

 

Not 100% sure it was a part of the package but I know it was optional across the line. This was the 70 amp alternator and takes a different wiring harness than the small case alternator.
This is the small case next to a large case version.

 

Whoa.. that ***** is humongous, garagantuan, and gigantic. Big.

 

And definitely NOT what OReillys has for an alternator for my truck. A little alt that puts out 34 amps on their tester

 

And it puts out a rip-roarin' 70 amps!
