308 GTB 1980 Springs

Could someone who owns a 308 GTB (1980 ish) please measure one front spring and one rear spring while fitted to the car and let me know the lengths?

I am changing dampers for a customer but I don't have the car here as it has been stripped for painting.

I have the spring lengths while fitted to the original Koni dampers and their free lengths but to work out the rates when installed I need to now the fitted length when carrying the vehicle's weight.

The new dampers won't take the 80mm I/D springs so I need to make some calcs to make sure I get the rates near to original as possible.

Any help with this would be greatly appreciated.

Kind regards Ian
