Here's a list of the Mopar kiloton cruisers torsion bar specs from Da Boyz over at the C Body Drydock. Get the 1.06" if you can...

Chrysler introduced a new C body for the 1974 model year. In that year all C bodies, Fury, Monaco, Chrysler and Imperial, shared the came torsion bars. They were 47" bars, same as the 1965-73 Chryslers.
The Plymouth Fury used 44" bars from 1965 through 1973. The 1974 Fury and 1975-77 Gran Fury used 47" bars.
Canadian market Dodge Polara/Monaco models used 44" bars from 1965 while American market Dodges used 47". All Polara and Monaco models used 44" bars in 1972-73 and switched to 47" for 1974.
The Imperial adopted the C body when it switched to unibody construction for 1967. It was basically the New Yorker body with a 3" longer front stub (and torsion bars). The 1974 Imperial used the same front stub as the other C bodies and thus switched to 47" bars. The C body Imperial bars do not interchange with the bars from the earlier D body (1957-66).
The difference in length between the 122" wheelbase Plymouth and Dodge C bodies in 1974 and the 124" wheelbase Chrysler and Imperial C bodies was in the back seat floor.
