The whole job might be 2.5 hours for front & rear.
I did mine in my garage with jackstands and a floor jack...the rear isn't that bad - you just have to unbolt a few things to be able to lower the IRS cradle.
The IRS only needs to be lowered a few inches, so there's no need to disconnect exhaust or driveline.
You basically disconnect the rear resonator supports, brake hose brackets, ABS harnesses, and the upper shock bolts, lower the IRS, unbolt the rear swaybar end links and brackets and reverse the process for the new bar install.
I used your little disconnect list above last night, to swap out the rear bar on my wifes 300c :thumbsup: :thumbsup:
In my case I was also swapping out the springs and shocks for those I got in the SRT Suspension kit.

It took me about 4hrs at a very leisurely pace...
That includes a 1/2hour+ search for my missing drive extension & later a 16mm socket
Having not done it before and being overly cautious... one thing I also did while dropping the cradle, after it was down about 2" (just before the front bolts let go) was to swap the much longer rear cradle bolts to the front position(turned them in about 1/2"). Then I continued to drop it down using the longer bolts up front just as a guide to make sure I didn't twist anything out of place. I left them in, the whole time. After I got the sway bar out, I had to drop it a little more to get the springs out... but the OP isn't doing that, so he shouldn't have to go as low..
Worked like a champ...
Hardest part was trying to spin the old sway bar the right way to cork screw it though the brake lines.
Kept snagging things.. once I got the right angle and spin, it came right out.
PS: If anyone ever tells you that a hemi 300c came with the same rear sway as a standard RT anything...
They are full of $#!^... no wonder the car leaned like a drunken old lady in the turns...
Below is what I pulled out
Stinking 12mm sway bar :notallthere: Replaced it with the 20mm STP bar above it
Improved the roll 200% and I haven't even replaced the puny 25mm front one yet.
