A lot of vehicles use the nylon bushings and I'm not familiar with their life as a spring bushing. They may work ok for light duty. I agree with Paul that the bronze are the best component for FFPW springs. The cost is cheap and they can last for 50+ years as long as you keep them greased. You'll find the bolts wear out faster than the bushings. Although steel on bronze bushings are available, I would avoid using them also.
If you decide you do want to use them, I would use bronze in the rear spring's rear eye (bottom shackle) and front spring's eye on the front spring. These are suject to the most force and wear.
