T400S Keyboard swap

[Saucey]

Hi I want to know if a T400S keyboard can be replaced by the "old" keyboards that are in T6x models.
I want to know if they share the same connector type to the motherboard.

I want to get a USB ThinkPad Keyboard, I've read on this forum that it comes from a T400s.
I want to try a project with it.

Also where could I get one for $60 used? eBay mainly has new and they are $120 usually.
