Re: NV4500 swap is underway

My plan all along has been to add a simple steel brace that sits above the tail housing and bolts to the upper two locations on the transmission and the upper three locations on the transfer case. It's a little hard to explain and I haven't yet sketched up a design. Just a couple ideas floating in mind. The point is that the top of the tail housing is in tension from the moment about the mounting points caused by the gravity force on the transfer case. My steel brace would allow the tension forces to be transmitted through it, in addition to the aluminum housing, directly from the t-case to the back of the trans. Unfortunately this does nothing to absorb the shear forces, but perhaps that could be mitigated if the brace also tied down to the tail housing mount locations. I'll need to think about it a little more before I start fabricating.

Or maybe the additional rear mount would be easier
