Did any of the Berettas have that stock?
Seems unlikely but thought I read one was made. Is it aftermarket?

No the only GM FWD to have it is the Cobalt SS and the HHR SS and both had it as an option not standard.

Didn't the HO Quad 4, with the Getrag, have limited slip available?
(I've heard it was available, but quite uncommon, even then. Think it was a Quaife.)

Or maybe it was just the Olds version. Or maybe a unicorn...

Olds Achieva SCX with the w41 quad was supposed to have a torsen limited slip differential RPO code G85.

500 of these cars were made according to Wikipedia.

Thanks! Didn't think I was losing my mind.
I seriously doubt that anyone would be able to find one now, though.
