torsion bar install questions.

I picked up a set of used torsion bars.
Came from a 68 Chrysler and going into another 68 Chrysler.
Is there a right and left
Is there a front and rear
Tips on clocking the bars on install to get ride height correct.
Thanx in advance.

The bar with the odd part number (like 779) is the driver, the even (like 778) is the passenger. The numbered ends are installed into the transmission cross member--though it doesn't matter as the direction of twist/load is the same either way

AS far as clocking, have the lower control arm as low as possible, and the adjusting bolt backed off when you slide in the hex.

By removing the upper control arm bumper you can lower the LCA a little further, this often helps.

Beautiful,
Thank you very much.
