They may all physically fit, but, I know for a fact that my 59 had at least four different sets of springs available for it.
These all different rates--wire diameter--number of coils.
If 55-71 will install in the pockets---that gives you a great variety of choices.
Personally, I would use the 56 v-8 coil for a convertable.
This might give a slightly lower ride height(maybe not), and would support the SBC. Quite possible have a stiffer rate for a firmer ride in the lighter HT/Sed cars.
Just a thought
