Does anyone know the amount of arc the front taper leaf spring had from the factory? Thank you... Craig

All I have is some data collected from previous discussions. It should be possible to measure the height with a main leaf by compressing its eyelet ends to the correct length (whatever that is for sure). There is agreement on the data for a height of 4-11/16" for lengths

I have a 1926 copy of an Australian spring maker setting chart which gives the measurement for a Model T Ford car front 7 leaf spring between bushing centre's as 31- 5/16 to 1/2 inch.

Not really important. When I bent each of my spring leafs into an arch in order to strengthen the spring, I didn’t worry about how much I bent it. The spring will find its’ natural arch on its’ own once the spring is attached to the perches, which are a finite distance apart, combined with the weight of the car. Once the car is lowered onto the spring, it can only go so far and no more. The more you bend the spring leaf, the more efficient the spring will be in absorbing the shock.
