ok, i am trying to put together what u have .......
a limited crossfire that u r going to put a V8 ninto Ok the limited has a 3.27 rear in now the limited transmission with an auto transmission will be fine,,, better,, would be the srt6 transmission ,,and even better would be the v8 transmission. The limited car has a small yoke both rear end and transmission. if you use the transmission from your limited , then the drive shaft from your limited bolts right in...
if you use the srt6 transmission you could swap the yoke on the srt6 and the limiter small yoke on both setups.
if u use the srt6 transmission you could use the front 1/2 of a srt6 driveshaft and the rear halt of a limited driveshaft.
if u remove the yoke on the rear the crush washer has to be crusher so that u have about 20 bs of torque on the pinon gear to turn.

again all transmission will work good, the v8 u r using is only 350 to 385 HP at the crank ,, for my car i had 590 HP at the wheels.
if i were u i would use either the limited tranny with your drive shaft that came with the car, or i would use the srt6 tranny and remove the yoke from the srt6 tranny set it aside.
install the limited yoke into the srt6 tranny iand bolt everything together send me a pm i'll send u my phone # and let u know even more info, on rear end choice jim
