how do i use these models?

How do i use these models? And how do I find out credit and copyright/copyright infringement rules and guide lines? I tried to download something once and all i got was a couple of rendered images. I would like to use some models for props in some rendered 3d art scenes. is this possible. I currently use sketchup and daz but their models do not compare to the realistic ones by artists on this sight. Also could not find the "feedback/wish button.

Dear Mr. Montoya,
If you are looking for precise parts for things such as designing additions to such parts, I would recommend simply going to the manufacturer's website. Oftentimes they will have CAD files of their more popular parts.
Cheers!

Thank you that is helpful. I will try again soon. And let you know how it goes.
