Help identify screwdriver for imac hard drive

[Andythed]

Hello

My mid 2010 i3 27inch imac had a logic board failure

Apple removed the hard drive so I could put it in a caddy to get my files

I bought a caddy but the hard drive seems to have a metal side bar along it, I guess the interface for the imac installation

Could someone point me in the direction of a UK screw driver on ebay which will remove this so I can place it in the caddy?

I am not a particularly competent technical person

Many thanks
Andy

From steps #13 and 14 here, it looks like a T8 Torx head driver.
