Transmission change
Can a mid-'90s 5 speed transmission be put in a 1977 Dodge W100 4X4; specifically one that has early '70s 3/4 ton axles, springs, and transfer case, and a 360 V8? If so, what "special" parts would be...

Gear vendors overdrives are pricey, over $3000 without installation, and only work in 2WD. Also, I'm not sure that the GV overdrive is compatible with the NP 205 transfer case in your truck. And you'd need new driveshaft.
The problem is going to be matching the spline count and mounting flange on the transfer case. Advance adapters probably has the one you'll need in stock. You'll need to look for a manual transmisison 3/4 ton or 1 ton Dodge V8 powered 4x4 truck from 1994 to 2002, which should have the V8 version of the NV4500 5 speed.
You cannot use the transfer case out of the donor truck, it will be driver's side drop, your truck is passenger side drop (front drive shaft). You could mate a late 80's / 1990-93 NV241 transfer case to the NV4500 (like the transfer case in my 1990 Ramcharger).
Personally, I'd go with the NV4500 and adapter, keeping the 205 transfer case... as a cast iron gear drive case, it's fairly bulletproof. You'd probably still be able to keep your current driveshafts, depending on the difference in length with adapter between the NV4500 and the four speed that's currently in your truck.
