What years did Chevy use the NP205 transfer case?

The NP205 transfer case was used by Chevrolet in various models from 1967 to 1991. It was a part-time, manual-shift T-case found in Chevy and GMC pickups during this time period. The NP205 is considered to be one of the strongest and most dependable transfer cases available due to its shear strength and ruggedness on the trail. It has a 1:1 high range and a 1.96:1 low range, making it highly capable for off-road use. The basic design of the NP205 remained unchanged throughout its production history, with the exception of a synchronized front output shaft briefly used by GM in the early 1980s.
The NP205 transfer case is a heavy-duty, gear-driven unit with a single piece cast iron case body and helical cut gears, contributing to its strength. It was used in various Chevy and GMC pickups from 1969 to 1993. The NP205 was traditionally used behind manual transmissions, and it is favored over the full-time chain-driven NP203. The NP205 was offered in both driver-side and passenger-side front output versions, with two input mounting configurations: figure-eight racetrack and a circular six-bolt pattern.
In summary, Chevrolet used the NP205 transfer case in their pickups from 1967 to 1991, making it a sought-after and highly capable component for off-road and heavy-duty applications.

NP205= gear driven, cast iron case, 1.96:1 low, very strong T-case. NP208= chain driven, aluminum cased 2.6:1 or so low range not so strong and vulnerable to rocks due to aluminum case. keep the 208. It Has a lower lo range, and i doubt you are going to break it.

Will a 700r4 bolt up to a NP203?

Adapting a 700R4 to a NP203 is either installing the spacer or the shorter output shaft onto the 700r4. Only one of those needs to be used, not both. Then bolting up with a TH350/NP203 adapter. A 27 spline input needs to be installed into the NP203 if it doesn’t have one already.
