FBO distributor counterweight springs

[hemi68charger]

Hello All,

I'm trying to determine which spring in Don's (FBO) spring kit is the middle tension. There's a dark phosphate (shortest), the a silver and gold colored version, both of those seem to be of equal length. I'm installing the advance plate he sells and, if it is in his instruction manual, I can't seem to find the description of the pairing of springs.

Thanks,,
Troy

the thinner the coil of the spring, the lighter tension it is...so if both are equal length, the one with the thicker wire will be stronger tension
