I could never understand why companies that sell big ticket items don't include things like instructions or troubleshooting manuals. I don't expect a set of instructions when I pick up a nut & bolt at a hardware store - it wouldn't be cost effective. - But I would like to see more information included with the complex expensive items. Not everyone is an expert. Sometimes dummies like me purchase from these companies and we really could use any extra knowledge they could provide. Throw on top of that - leaving out necessary fasteners or supplying ones that are the wrong length and it could be a recipe for disaster. This Tremec has been modified to handle in excess of 1000 HP. I could imagine some guys using the bolts that they'd sent me and having everything come apart on them.
