That is a heck of a list! :thumbsup:
I may be biased though, absolutely everything on that list is on my Duster with the exceptions that I run the 13" cobra style kit instead of Viper brakes, have different spring rate AFCO's and I run Hellwig sway bars instead of Hotchkis. Literally everything else is the same. Prices have definitely gone up on some of those items since I installed them on my Duster though!
Really only a couple of suggestions, the first one being that I think the AFCO 20231HD's will be too stiff for a handling car, and will have too much arch (6 5/8"), which will put the *** end up in the air and upset your roll center. Those springs have a rate at 166 lb/in, which is super high. I run AFCO's on my Duster as well, the now discontinued 20231M's. They're 121 lb/in and have the 5 5/8" arch. Unfortunately with the return of the Mopar Oval track springs the 20231M's were discontinued. If you want to stay AFCO, I would suggest the 20230's. They have a 5 5/8" arch and a 142 lb/in rate, which is the lowest rate currently offered by AFCO (which is a bummer IMO). I like the 121 lb/in springs on my Duster, which is also a 108" wheelbase like your Barracuda, and runs 1.12" torsion bars with a small block. If anything, my Duster may be heavier since it's a '74, although I have ditched most of the heavy '74 stuff for the '71 versions (bumpers, bumper mounts, etc). So honestly I'd be more inclined to replace the AFCO's with Hotchkis leaf springs in your list. Even with the 20231M's and the spring sliders lowering the car about 3/8" compared to shackles, with 27" tall rear tires I'm considering a 1/2" lowering block to sit the car flat.
How come your spring sliders are racist? :poke: (looks like you've got a typo :p )
But seriously, another option is the Calvert rear spring sliders. Unlike the AFCO's, they have an angle built into the slider track to better match the spring. It depends entirely on how you're planning on mounting the spring sliders, but on my car I mounted them flat because they sit against the frame bracket, so the angled track would have been beneficial for better geometry. So far it works fine the way it is, but if I was going to start from scratch I'd use the Calverts this time. They're also less expensive than the AFCO's, but the quality is still great (I have a set of these too, just not on the car).

You shouldn't need a leaf spring bushing kit (LSBK30). Your new leaf springs (regardless of brand) should come with front bushings, and the sliders will include the aluminum rear bushing.
Don't spend $35 on torsion bar boots. These work, even with 1.12" bars. I have them on my Duster and Challenger
