4l80e Swap

[softballnrd27]

I just bought a 98 4l80e that I am installing into my 73 and I need to get a parts list and tips before I start this. Trans fluid looked good and didn't smell burnt and I am pulling the pan to check the internals this weekend. My plan is to install it as is and compile the parts to build it up right.
Here are the truck details and stuff I have:
2004 5.3 243 heads and a small cam, all trans wires have been removed from the harness so i will have to put those back in.
A th350 is currently in it.
I have a tubular trans cross member on the way.
I'm ordering a 4l80e trans plug and a slip yoke for it.

Now on to the questions:
Shift linkage, what to do here?
What about the 2 speed sensors and the MLPS? Where do they go/come from?
Cooling lines -6 or -8? (Forced induction in the future)
I'm still researching the process so I hope to find some answers.
