Big69C20,sounds like you are familiar with
this rearend.Is HO72 a code for this rear.I
know hardly anything about them.They seem
pretty stout looking though.I have one under
my 71 3/4 ton 4x4 pickup.Gearing is either
4:11 or 4:56 I believe.I know that it is
popular to put a big Chevy 14 bolt in when
these go south.Must be parts availability or
something.Mine seems to hold up well.Do you
have any info? Thanks.
