the t-case appears to be a np203, you might find a tag after you clean it up

Looks kind of like a 203, from the linkage. Can't really tell for sure.

It's a 203, worth about a dime a dozen unless it came from behind a turbo 400 (32 spline input gear) or the rare 1 1/2 year production 465/203 combo (10 spline input). You posted turbo 400. Take the front cast iron box off and sell it, unless you're building a reduction box in a wheeler. Verify the spline count on the input. 27=turbo 350, 32=turbo 400

NP-203 for sure.. I have one you can have when ever you come to Las Vegas
The Turbo-400 is the best of them. Mine is a SM465 four speed set up.
