Holy crap! You broke a solid rocker shaft? I've broken stock and heavy duty thick hollow shafts but never a solid shaft. As far as I know, the only vendor making solid shafts is Hemco.
For all i know this shaft was made in china At least that's kinda what I'm hoping....I hope there isn't something funky going on that's going to snsp another shaft
I see from your other thread that your shafts were the heavy duty hollow shafts, not solid shafts. Ditch those for some real solid shafts if you can find a set. As I said, I bought a few sets from Hemco Machine a couple of months ago. These puppies aren't going to break.
