I Don't know if this will help but when I am doing a build and I want detailed information I go to a couple of Blueprint sites,
One is free the other makes a small charge but does give more detail.
They are---
The-Blueprints.com - The largest free blueprint collection on the Internet - 15000 vector templates for sale
And--------
Free Blueprints DataBase for 3D modeling ?
Type into the search box what you are looking for and you will get a detailed list from which to choose.
I hope that helps.
Shaun.
