Can someone tell me how the rear brake lines on my 72 K10 should be routed? (Pics)

Recently purchased this truck...trying to go through it, order parts, and make her safe to drive!

It has been lifted 4", and previously had a body lift (which has been removed). It looks like the PO didn't bother to extend brake lines (front or rear - got the front figured out - I think).

Is the bracket where the top of the rear flex line connects look 'normal' to you? Or is it 'bent up'?

It looks like they just removed the hold down bracket from the rear diff and bent the lines up to make it work. I plan on ordering new hard lines and a new extended rear brake line so I can get it back on the diff. The stock flex line is around 13-14", not sure how much longer I need to go? Looking at parts online, it appears an 18" line is what is called for with a 4" lift. Not sure if that will be too short though if indeed the upper bracket has been bent up and away?

Also, should there be 2 tabs holding the brake line to the diff (1 on each side)?

I've been looking at the extended lines offered by Inlinetube, ORD, and others. I don't suppose anyone knows of an oem style rubber line that is extended? I found the thread in which Special-K gave the part #s for extended front lines using C20 parts (awesome - going to buy them) but it looks like for the rear aftermarket is the only option?
