when installing my new torsion bars, does it matter which end goes into the control arm or rear mount. the bars are mare marked 781 and 780. and are marked L and R, but one end has a 3 digit number and the other some letters, along with the 780 and 781, didnt know if it matters which end goes forward? , but just wanna make sure

Thanks

Duane

Direction does not matter but the side does. That's why the are marked.

How sure are you about this? I don't know myself, but it seems like you will be twisting the torsion bars in the opposite direction (clockwise/counterclockwise) and if they're used bars, I would be afraid that twisting them the opposite direction after 40 years might break one

I put #s to rear, what I was always told.

Side matters direction does not matter. Seems like the factory put the numbers to the rear also, can read them in the car most times.

You can be sure by doing a test with an envelope. Hold it on the short ends and twist it, write on the 4 corners which raise and which lower, now swap ends and twist the same direction, the same corneers are raising and lowering.
