Like the title says, I'm tired of seeing all the "what do I need for this" etc. posts and I really just hate saying "Search, you'll find answers." While the answers ARE out there they aren't 100% easy to find. I found them on the site, but I've also looked for a while.

This should be absoloutley EVERYTHING you need to complete a K20/24 swap, Minor variances will be there as this list is meant for an EG only because It's what I own However it should be 95% of what you need for EK/DC2 aswell.

That should be it, Correct me if you see something wrong. Hopefully this stops all the "Zomg what do I needz" posts...
