Where to start front suspension

[CTK]

I have started measuring and working out options for control arm pivots on my 55 TBird
i am using m11 spindles with 2/12” drop. I can lower the bottom control arm pivot about 1” which brings it to almost level. They are about 17” long
My first question is anti dive? How do I do this correctly?
And lower control arm length, if I can make them and few more inches longer, should I?



I will also be lowering the upper pivot points to match the amount changed at lower pivot, plus 1” for the spindle being 1” closer between joints, compared to original.
I am also trying to work out if I should include 1/2”-1” extra. Shelby mod. Style.
I am yet to measure completely roll centre but read it should be about 2-4” from the ground.

I am a newbie at this and appreciate any help I can get.
