[Chevelle-list] 12-bolt rear

Hi Larry,

It's a 4x4 with a mild 350.  Tires are 33" and currently the gears are stock
3.08.  I was just thinking about what to do down the road and have
considered the 14 bolt route but decided against it.  If/when it comes time
to upgrade, I'll probably see if one of the aftermarket companies can put
together either a 12 bolt or 9" for it.  For what I intend to do, either one
of those will be able to handle it.

Herb

  Herb:
  Is this a 2 wheel drive or 4 x 4 ? I ran a 500 hp 454 in my 4 x 4 Blazer
and broke 3 -12 bolts (big tires-373 posi). Finally put a 14 bolt corporate
(410) under it and never had another problem with rearends. But then I had
to deal with 8 lugs. Incidentally the car 12 bolt ring & pinion is the same
size as the truck 12 bolt ring & pinion. (but I do not know if they will
interchange).
