Looks great! You’re going to love having overdrive
Lots of ways to skin a cat with mating a NV4500 to a NP205’s. I went the avenue of replacing the long 32 spline input on my round 205 to an early short input to avoid using the AA spacer between the trans/tcase. That also prevented the need for any driveshaft mods.
I used this input gear in my 205
And removed this one....
