2) Transfer case Crossmember. I used the stock T221 crossmember. You will need to re-drill the holes through the crossmember into the frame rails due to the length of the new transfer case and adapter. I did this with a 12" long 3/8" drill bit. Using the stock member caused the top of the transfer case to hit the cab floor, so I notched it out. And yes I do have a high hump tunnel and just installed new cab mounts, and it still hit.
2a) I've read that if you use the NP205 transfer case crossmember you will not have this problem. Or you can put spacer between the member and the frame rails.
