72 ABS brake lines

[josuito]

I have a 05 yukon denali 6.0 4l80e 4WD which I removed the whole body to sit my 72 k10 suburban.

I have a few questions?

1- I want to know if I need the ABS system or can I just use my 72 booster and run new lines to each wheel? I'm planning on towing my tow hauler.

2- If I keep the ABS do I have to use the computer to run it? (I have the 05 booster hooked up still).

I kept everything of the 05 just in case I need something later.

Thanks in advance.
