rear spring recommendations

Hi,
I have a 70 duster, installing a v8 and an 8 1/4 rear to replace my slant and 7 1/4. I want to replace the rear springs, looking for advice on what you may have bought and maybe photos to show the stance. I like the slightly higher than stock look, but not too high. I would be interested in what you paid and where you got them as well. thanks!
