i have a 70 charger 500 that came with a 318 with the torsion bar broken off. i am changing the torsion bar crossmember because it rusted out. there is someone who is selling a set of torsion bars from a 70 roadrunner with .925 at it's biggest. would it work for my charger..? thanks oh i am putting in a 440

Look at Firm Feel, or Performance Suspension Technology, or any other front end parts supplier. They have all kinds of NEW torsion bars for your B Body. Bar size will be a selection you need to make, depending on how you plan to drive the car . . . bigger bar, stiffer suspension, better handling. Smaller bar, mushier suspension, less handling . . . all depends on you . . .hope that helps . . .

i am guessing that it would fit my charger from what you are saying. thanks..!!1

i am not sure about that, the wheelbase would determine if it would fit. The bar diameter is indication of stiffness. The correct length would need to be determined to see whether or not it would fit the application.

1970 Charger torsion bars are 41 inches long. With a 318 engine they should be .880 diameter.
With a 440 engine they should be .920 diameter. So yes the ones you found should be correct for you.

thanks everyone..!!!
