Determining the correct 5-leaf springs - 69 SS 396

[nuch_ss396]

Hi all !

I need to solicit some help from members here regarding the
selection of the correct front & rear leaf springs for my
69 SS 396 Camaro. I am nearing the completion
of my restoration and now I have to look into selecting the
right springs.

While doing some preliminary research, I have come to learn
that there may have been many different factors that went
into the spring selection on big block Camaros. Was this
true for front and rear springs, or just the front springs?

I've see posts ( on several forums ) that dealt with the
problem of one end of the car sitting too high, or too low
after springs were rebuilt/replaced. How does one avoid
this problem?

So, what I really want to know is this: Is there some type
of formula that Chevrolet used back in the day to determine
the correct springs for a particular application and does
anyone know the formula or an alternate way to select the
correct spring combination?
