On the test fitments I've done, they share the same segment lengths as an A body.

Is this for the yellow Duster?

That was the initial idea, but no, not anymore. The yellow car staying all original. I do have another 71 I'm doing, it's going to be the guinea pig. I started this post quite a while back, I still haven't seen any torsion bars offered to make this "Total" vehicle system offering complete? Any updates?

No real updates. The 68 is about 90% complete. It's been too hot to work on it so it's a little at a time. My last day at work was this past Friday so I'm officially retired. Now it's packing boxes for the move to Mesa.

I have some of the parts of the TVS on my car and I live in Metro Detroit where there probably are the worst roads in the entire nation.

I have:
-Hotchkis UCAs
-Hotchkis F&R sway bars
-Poly LCA Bushings
-RMS Strut Rods (Hotchkis ones are close enough so I doubt it makes a difference for handling)
-Hotchkis Subframe connectors
-Hotchkis/Fox Racing Non-Adjustable Shocks
-Firm Feel 1.06 Torsion bars
-ESPO 6 leaf "340" Springs at stock ride height, offset shackles
-Borgenson "first design" steering box
-Currently 225-60-15 BFG G-Force Sports
-1.5 deg camber/ 3 deg caster (will add more caster in the future)

I have to say that unless you're on a really, really rough road it rides better with this setup than the more OE stuff I had before. It corners extremely flat, and feels very balanced, like a totally different car. I'm not sure I'd go over the 1.06 torsion bars unless you're only autocrossing or road racing. I keep my rear bar in the middle setting for now, probably the most neutral for the street.

I do not have the rod end steering links or the rear springs so I can't comment on those. I do experience some minor bump-steer, but not terrible, and I haven't had any decel wheelhop or anything with the rear springs (poly bushings), so I'm quite unsure how much performance would be gained there.

I have a set of 275-35-18 tires for it but just need to get the wheels modified and I'll be set to go there.

Here is a handy little chart from Mancini Racing with all the leaf spring dimensions. also a link for AR Engineering is attached for all new front hangers available. The leaf spring front section dimensions are shown for each style front hanger.

Other differences for the frame connectors are the wheelbase changes in Dodges 116" for 1962, 119" for '63-'64, and 117" for '65. Plymouth stayed at 116 inches '62-'65.

Very cool info! I'll have to make a copy of that for future R&D.
