Editing display of the "Last Post" column?

[xdoomx]

Hi,

I have a client who wants the display of the "Last Post" column on board index to be modified. I need to remove the thread title, leaving only the username of the poster and the date. Basically it should display like on forumdisplaypage, only this will be for board index. I can provide screenshots if what I ask isn't clear.

Basically I just need to know which file do I need to edit to accomplish such a thing.

Thanks!
