The gear selector shaft in the side of the Camaro trans will have to be swapped with the one from the truck trans. The truck one is longer for the gear selector switch. I don't think the tail housing will be an issue, just the torque arm holes on the Camaro tail won't be used.

 

only thing needed to change is the gear selector and tailhousing thats it and 5 pinion planets came out in escalades denalis gtos etc as stated in last page

 

The shifter shaft is the same. The bracket is different.
