I gave some T6 Chubs to a guy who needed them for his 6.1 He made them work. I dont think anything else will work but im not sure. I know the arms and steering blocks were changed as well. Im not sure if you can use the rear hubs either...probably but you would have to account for the toe angle.
Good luck...its sad when we cant get AE parts .....its one of the reasons i went with the TC6.
