Header installation Advice.

I picked up a cheap set of Jeg's headers (Based on the Hooker Comps)(Yes, the ones that go through the draglink)(No, because I can't affords TTis), and I'm looking for some tips and tricks on the installation. This is what I've got.

Power Brakes.

Any help wopuld be huge! I attempted this before, and gave up. but not this time! I'm going to do it.

Thanks!
