Come one people. Its not that hard. I don't even find it tedious or stressful. Just take your time and check everything. If you are good with your hands/and have done work like this somewhat before, you could, cut the IFS off/weld everything on day 1. Days 2 put everything together. Day 3 would be for fine tuning, odds and ins and taking her around town to show your friends.
And if you really need the truck DD, the SAS parts don't interfere with the IFS. So you could weld the front hanger on/Frame tubes on and then focus on the Axel. Then when your ready, Cut the IFS off, simply bolt the axle up and weld the shock hoops and PS box on.
I think the difference here is, you can take two different approaches to doing a SAS. You can cut off only what is not needed, which makes the job faster, but leaves alot of excessive stock
behind. Or you can take your time and start eliminating all that stuff and end up with much cleaner looking truck. Like the torsion bar brackets. Most people dont cut them off, and to do so you have to move lines around and out of the way, so its a pain in the butt. But in the end you are probably happier with it being gone and out of the way, plus it make future mods much easier.
