I never quite got to grips with what vehicles the right NP435s came out of. I think mine came from a vehicle that wasn't "on the list".
The important thing is that it is a 28 spline output shaft.
There are two bolt patterns for the t-case/tranny mount. "A" shaped and "square". Adapters are available for both, but you should do more research, I put mine in over 10 years ago, and I don't remember much of what I read then.
Mine was from a 69? F150 4x4 w/28 spline & A shaped bolt pattern. But, according to this:

You'll need your 3 speed bellhousing, the FE block bellhousing won't work on a 302.
