drop spindles and coils

so im thinking of getting two inch drop spindles for my 69 camaro... my question is do i have to also get 2 inch drop coils or can i use my stock coils.... also can i use 2 inch drop coils even if i have not yet put in the 2 inch drop spindles.... any ideas im a little confused with this

you can use one or both. if you want a 2" drop, use the spindle or the springs. you want a 4" drop, use both.
