..it's a good read. There's a less expensive alternative to an original T-Bolt via a company called Crites (sp?). I know that they were building accurate clones w/ 460 crate engines installed but I'm not sure whether they still do that. They also sell the T-bolt conversion parts. A buddy of mine got the shock tower kit w/ parts and templates for cutting. It's worth checking on considering that there were only like 100 of the real ones made with ?? still surviving.
