Had my 6.2's for 13 years and have never suffered a broken bolt and I DO have the bracket.

Had a co-worker with a 6.2 truck for a few years. Didn't know he had it untill he gave it away. I asked him why the heck he did that (and why he didn't give it to me!). He said he got tired of replacing starter bolts. For some reason they kept shearing off, he said. I asked him about the bracket. "Uh, what bracket???"
