I replaced the transfer case mounts with poly mounts today. I do not know what conversion kit was used by a PO to install the NV4500 in my truck but, it must have been very cheap! Of course the extra HP?TQ that the truck now makes and the 3300 rpm power shifts may have contributed to the metal fatigue.
Here are some pictures of the transfer case adapter, or what is left of it. the yellow marks are cracks. In the other picture you can see where the bolts had almost pulled through.
