/6 to V8 swap

Ok not sure if this is the right section but here it goes, I am swapping my 1975 Duster /6 engine, trans and rear axle. I had the old 7/14 rear axle and 904 trans, I now have an 8 3/4 rear axle set up, and a V/8 904. I am swapping the /6 k member to the V/8 K member, dont have everything mocked up yet as I am in the process, was wondering if I am going to need to swap the drive shaft?

No. If swapping same trans to same wheel base, it's not necessary. The 904 has the same length tail shaft, unless it is used w/4wd, and it attaches to the cross member at the same point regardless of /6 or V8.

Also do I need to swap the torsion keys when switching to the V/8 bars,

Keys?

also what is the diff between the V8 /6 bars?

Diameter. IIRC the 225 w/ A/C used the same bars as the 318 w/o A/C. The 318 w/ A/C & the 340 used the same bar, .870, all 383 cars used the .890 bar. The 225 bars work fine, but very good HD gas shock needs to be used with them. FWIW, when I converted the Demon, I used a '75 K-frame w/sway bar, 1.0 T-bars, and Monroe Gasmatic shocks. Works like a champ.
