    I just swapped in an NP205 into my 70 K5 - the prior owner said it had a Dana 20. I have all new rubber body mounts and I am using polyurethane transfer case mounts, the onese that are used to attach the adapter to the crossmember.

    The NP205 is just barely touching the bottom of the K5's floor. I have not been able to torque down the bolts going through the crossmember to the adapter but I doubt that will pull the NP205 down much. I need to move the crossmember back approximately 3/8" to make it so I can bolt the adapter to the crossmember.

    What kind of clearance do you all have between your floor and your transfer case?

    As I stated at the other board, I know for a fact that the 205 crossmember has about an inch more drop than the Dana 20 crossmember. I tried to put mine back together with the Dana 20 crossmember when I swapped to the 205, and I had the same problem as you. Luckily, my parts truck was a '72 Blazer that came with a 465/205. When I compared the crossmembers up close, the difference was obvious. With them sitting a few feet apart, you never would have noticed. The t-case hits the floor pan behind the hump, not a high hump/low hump issue.

    This is the best pic I could find YJ.
    There couldn't be more than an 1" clearance between the T/C and the floorpan.

    Thanks for the pics and info. Mine is actually touching the floor. Went ahead and bought some stuff today to add 1" spacers to drop it down. Hopefully get that done tonight or tomorrow.

    I do have the correct bracket to connect the NP205 to the frame so hopefully it lines up when I drop the t/c 1".

    The frame brackets are the same for either t-case.

    Thanks, because of some stuff that came up I haven't dropped the t-case yet, so that still helps.
