Question what is the length of a stock rear spring?

[OLD MAN]

SO I have long since sold off or thrown away any stock springs I have had over the last 30 years or so.

So I need to find out if anyone know off hand what the stock rear spring rate is?

And what the free length of it is?

Thanks, Daryl

Also need a pair of used rear adjustable (Short) spring sleeves and colliers.

I have a set of long ones, thinking I may need to go with short ones?
