Attempting my first build 72 K5

[72K5CSTDarkOlive]

I have another question for you experienced folks. I want to avoid running into the same problem I did with the steering tie rod and stabilizer. I had to disassemble the leaf springs from the axle to get those parts on.

Based on what I have assembled what would be ideal steps in finishing the reassembly. Yesterday, I finished putting the drag link, pitman arm and the power steering gear box to the frame. I also finished the brakes on the rear axle

I have a couple ideas but from your guys experience what would be the best order to start assembling the rest of the parts?

I was thinking:
1. Route the fuel and brake lines (since I wont have anything in my way underneath)
2. Install the Gas Tank ( i figure that will be a lot easier w/o the leaf springs and axle in there)
3. Install the Rear Leaf Springs
4. Rear Axle
5. Steering shaft (or should I wait till after the engine is in.. Is it easier to get the engine with the headers with the way it is now?)
