Building a new spring, need advise

[36coupe]

I need a front spring for the 37 front axle that I have. I went to take the original one apart and more than half the springs where broken.
I’m am going to get a local spring shop to make one.
I’m going to ask for a reverse eye. The original leafs are only 3/16” thick and the replacement will be 1/4”. The main is about 41_1/2” eye to eye.
Do I have to tell him the arch that I want?
I’m thinking about 8 leafs will the same thickness as original.
I want the front to set lower than stock.
I plan to take everything into the shop.
