Does this Torsion Bar number mean anything?

[67cuda360]

Hi, I'm rebuilding my suspension on my 67 Barracuda and I had to take my Torsion bars out to get to some stuff. While they are out I'm trying to figure out which type I have, do these numbers on them mean anything?

It's kinda hard to decipher the top numbers it seems like a either a 8 or a 6 or a "G" for the first letter and then 3L (I assume L stands for Left Torsion Bar) and then the bottom number is 456.

I measured the thickness of the bar in the center and it seems to be .87 so am I safe in assuming I have the stock small block 318 (with airco) and 340 bars (120 lb/in spring rate)?

The ones on the other side of the bars is the one you need to know.889/890 and so on

The measurement should be decisive, in any case.

Perfect, I'll have a look on the other side of the bars to see if I can find any numbers. Thanks
