Floor mount?

[884x4310ci]

Hey guys I am in need of a floor mount. The one where the body bolt threads through. And you weld your floor pan too.
I looked at rock auto and could not find them. Maybe I looked at the wrong place.
Seen them on eBay but don't want to get it there.

Front, back, center?
