Leaf spring wheel alignment

[MAStuart]

I need to keep my scratch build moving forward. What specs should I be shooting for on the alignment on rear of a leaf spring car. I would like specs for street use and open track.

My rear suspension will be nonadjustable as on an original car. I need to get a rear spring built. The length needs to be right for the camber curve.

It would be very helpful if some could give me the center-to-center measurement of the rear shock mounting bolts. This measurement needs to be as it sits on the ground just like it is driven. I dont know if its even possible to get this measurement as the car sits.

Also what shape is the leaf spring in the on the ground driving state? Is it straight or flat, curved upward, or curved downward .

With the length between the shock mounting bolts and the shape of the rear spring, with the alignment specs. I should be able to calculate the correct spring length I need to have made.

I sure would be nice to get it right the first time. Custom made springs are not cheap if you dont get it right.

Thanks guys if you can help. Mark
