rear leaf springs

I have a 65 coupe 289, 4 speed car and need to replace the rear springs. The car has 15X7 magnums with 225 60R 15's. The wheel opening sits about even with the top of the tire now and I would like to maintain that "stance". Mustangs unlimited has a GT spring, standard eye, mid eye (etc.), 4 1/2 leaf springs, and so on. Anybody have any suggestions on which spring will keep approximately the same ride height?

Thanks

I just put a set of the mid-eye's 1" drop springs on my 66. It sits about 1/2 to 3/4 inch off the top of the tire. I have 17x8s with 245/45R17 though
