Mine has an machined aluminum plate and a hybrid gearbox output shaft.
I'm running a BW T-18 that Timm reworked. So a large part of the cost
was for him to go through the gearbox and install the new output shaft.
For me the adaptor included the gearbox as part of the price.

This is the basic process of what Timm does for the T-18 & I assume the
NP as well.

My transfer case is mounted in the factory stock location so it can use
stock prop shafts. It just means the engine is a tad rearwards
providing more space for the radiator without moving the radiator
bulkhead out to the front.

I initially voiced that concern to Timm when I learned that two gearbox
output shafts were to be welded together. He said he has never broken
one and would guarantee for our lifetimes. I figure if anyone could
break one of these shaft, mad driver Timm could.
Sounds to me like you and he are doing basically the same things.
