i ran stock steels and fibers for quite some time but i did change the springs. i put barnett springs, well three and three stockers. you can buy stock individual fibers or plates, but while i was there id just put a barnett kit in it. If so dont use the rubber cush rings thats on the stock clutches. and i wouldnt use all the heavy springs (to much clutch pull). the last set i bought came with stock replacement springs and heavy springs i just split em up 3 & 3. i take my steels and find some kinda rough concrete and rub in a figure 8 pattern then clean em good with a scotch pad. hope this helps.
