So GM doesn't make a 12-bolt any more ? My 396 Chevelle & my 454 Monte Carlo both had em & they were dead reliable & never made a sound . Why can't some one step up to the plate & sell one that will bolt into our F-bodies without any mods for a decent price ?

depends on what your definition of a "decent price" is.
Moser and Strange both make 12 bolts that will bolt right in to our F bods. I have a Strange unit in my 94Z.

I guarentee you, if GM made a 12 bolt, even under the Perf Parts division, it would be relatively expensive, if not more.

Yeah , well it may bolt right in & handle the abuse but its also loud as hell . Who wants to drive around on the street & have to listen to the rear end howl like a banshee ?

I feel that the torque arm mount places a lot of stress on the 12 bolt housings. My Moser 12 bolt in my '99 Z28 was dead quiet until I took it to the track and came out of the hole at 4000 rpm. i hear this all the time from other people with Moser and Strange rears, so it is not an isolated incident with just my car or with just Moser. If you put a Moser 12 bolt into a '70 Chevelle, you can beat the snot out of it and you won't get any gear noise.
Because of this, I recommend the Moser 9 inch. The torque arm mount does not seem to stress the housing on the 9 inch, as they do not pick up gear noise after being subjected to drag strip use like the 12 bolts do. Bob

so a moser 9" w/4:10 gears.true trac diff 35 spline axles on a non abs car would need what kind of a torque arm?

Don't think they make a trutrac that will accept 35 spline axles. I think it is only available with the detroit locker. I tried to get a tru-trac with my 35 spline axles and was told they don't have them.

I bought mine used and beat the tar out of it and its still pretty quiet. It does have a little gear noise but it certainly does not howl like a banshee.
