Best Disc Brake Conversion

[69ROTROD]

So I am deploying to Bahrain in December and after a lengthy talk with the wife, I have approval to get my truck into "daily driver" status instead of buying a new truck when I get back.

I want to start a build list with approximate costs associated.
The truck already has a GM Goodwrench 350 with a Rochester quadra jet and flowtech headers. So that is pretty good.

I am seeking your wisdom with my plans...here is what I have currently.

1. Power disc brake conversion
2. Replace all brake lines
3. Professional exhaust (mines all clamps and cherry bombs)
4. Rebuild/refresh tranny (I am doing a filter/gasket change this spring but may want it pulled to do more when I get back)
5. Read diff inspection/flush.
6. Rear brake shoes/drums.
7. Radio install

I have thought of adding power steering but I am not sure what the cost would be...

Thanks for any advice you can give. I would also love to hear about any vendors that you recommend.
