No. I am guessing you have the NP205 since you didn't say. If thats the case you will need the TH400 to NP205 adapter, which is $$ if you can even find one, from a 77-84 K30 1 ton truck. Then you will need a 32 spline input gear for your transfer case, about $150, and then have the bearing hole bored out for the larger bearing, around $40-50.

No, I believe your 205 is a 10 spline version, so you will need to find the correct adapter, and input for any tranny you want to install.

Or just find a TH400 with the transfer case and correct adapter, and then sell yours.

Yes you should be able to use a ratchet shifter with a 2 inch body lift.
