Fast,

yes, according to the info I can find, there was an HE4 code, 3.40 ratio axle. It is in years 76 - 81. I don't know anything about it other than it is for real. I have never seen any info to it being in a truck. From all the places I've seen the only 3.4x I've seen is 3.42. These were in both 10 bolts and 12 bolts.

Maybe someone else can help here. Now you have got me thinking. It doesn't matter if it's a GMC or Chevy BTW.
