3spd to 4spd?!

So I basically need a parts list of what I need to put my A833-OD in my '64 Dart 170. My Dart is still rocking it's factory equipped 3spd on the column.

I've got the trans already, a '76 aluminum box, with the levers rods and shifter assembly, I also have a aluminum slant 4spd bell. I'm needing the covers and fork assembly and am not sure if the rock Z-bar will work.

Which fork do I need?
Will the clutch assembly and TOB from the three speed still work?
Is there anything else I need?

PS: I know I have to get a new driveshaft. I also added a 8.25" rear end which has a longer about than the stock 7.25". Is there a factory driveshaft I could use instead of having one made?
