Dodge D60 leaf springs

[cliff]

Hi Guys. I am building a model of a D60 as shown and have all the measurements to do it except for the length and width of the front and rear springs.

So can anyone help with

A/ length of springs eye bolt to eye bolt both front and rear

B/ width of spring leaf both front and rear.

Thanks guys.

The pic is of the type of vehicle I am doing. This one I took at Kingaroy Queensland 18 months ago. Sad to say this one, after the removal of a few parts, went through the crusher in June last year.
