    Just for the record, I'd keep the Th700, but if you prefer to drive a manual, the 465 would bolt in without great difficulty. You'll have to hang a clutch, so start looking for the bracketry. Later model hydraulic stuff would be nice. A 465 from a 208 application would bolt right up to your t-case.
    A 4500 would also bolt up to the 208, but they're a more expensive trans, so you have to decide if the overdrive is worth it to you. I like having an overdrive, it lets you run lower diff gears and still drive on the highway. Just leaves it more versatile.
    A donor truck would be a good place to start....

    Madmax I started rounding up the parts nec. to do the same swap but decided to keep the 700R. If your not to far I have the following, pedal setup, scattershield, floor pan cover, frame bracket. no tranny or t-case but have access to them fairly resonable. I am in Colorado just outside of Denver. Iceman

    One thing I forgot to mention is that the 465 uses a 32 spline output shaft to hook up to the 208, the th700 uses a 27 spline shaft. This means you will have to change the input gear in the 208 to the 32 spline, or find a 465 with a t-case already attached to make it work.
