Adding Bronze Bushings to Ductile Iron Rockers

Thanks for all the discussion around this. I've beed out of commission getting a tooth pulled and had not been able to check the thread. The pictures of the bushed and un bushed rockers are gold. That tells me 90% of what I needed to know. My biggest stumbling block now is cost- at $16-18 per rocker for bushings plus the set needs adjusters, I'm looking at well over $1000. At that point, I might bebetter off looking for a new set.
