I have the 4r70 with aa adapter and have modded the crossmember per the aa instructions, turned out nice. thinking of going with the behemoth strong box with the dana. i like the versatility of the strong box. looks like with the awd the crossmember will have to fit the stock tailshaft. i saw spareparts stuff on his thread for his 205, that may be above my skill level. i remember reading a bunch of threads before i decided to mod my stock crossmember for the aa adpater.
