Location: St George Queensland Australia | Hi All, What thickness should the torsion bars in a 57' plymouth 2 door sedan be, to run a big block? Would a pair from a 58' dodge sedan with factory big block be the right one's? At the moment the 57' has the standard one's for the 303 poly installed! Thanks in advance, Glen

Location: bishop, ca | The standard 1957 Plymouth V/8 torsion bars are P/N 950/951.
They would be 1" diameter.
You should put on the bigger, 1.04" (IIRC) easy-to-find 952/953 bars which are found on the 57-58 Belvederes and Furys, and on the 57-58
Dodge Royals and Coronets.
Any of the large national wrecking yards should have these car models, which can provide their T/bars to you.
You might, even, be able to do some price-shopping on them, too.
Before you do order any T/bars, you should get under your car and look at the exposed butt-end of your car's T/bars, to confirm
whether you have the 950/951 or the 952/953 bars.
Those numbers will be raised cast-in numbers on the bars...just gotta clean-off the grunge that may be hiding them from your view.
Here's an image for you...

Location: Upstate NY | That brings up a question for me. I have the arrows indicating direction on one end and the numbers on the other. I was under the assumption the arrows were in the back and the numbers up front. Obviously not so from your picture!? |

Location: Netherlands | Front to back doesn't matter. The twist is the same.
Left to right does matter and the bars should be kept on the correct side of the car.

Location: bishop, ca | Dodge/Plodge doesn't matter; just confirm the Part Numbers on them.
And, the 'even' numbers go on the right side of the car (looking Forward, from 'inside' the frame).
