what is the correct match 780 & 781 or 779 & 780. In the charger,RR, Suber Bee restoration guide it shows 779L for left & 780R for right. brown paint dabs to identify. Left has two brown dabs & right has one brown dab.

What year B body? 780 and 781 are 440/426 66-71, .92" with brown paint, 778 and 779 are listed for a 440 in 72, .90" with aluminum paint.

found my answer in the arcives:
My notes indicate the B-body Hemi torsion bars were left #781 & right #780 bars with diameter of .92 inches.

The base Roadrunner w/ 383 used HD bars left #779 & right #778 bars w/ diameter of .90 inches

In my parts book, the 780 & 781 bars are listed under Heavy Duty section and are specified for all 440, 426 applications and also under "extreme Duty" applications.

The 778 & 779 bars are listed also under Heavy Duty for all applications except 440 and 426 engines.

Hope this helps.

Plus 383 B and E cars automatically came with the 440/Hemi suspension (Xtra heavy duty) if they were equipped with an axel package like A31, w/3.91 gear or A36, w/3.55 gear ratio.

Johnahah, i agree 100 %.
