Transferring license to computer with new hard drive

I have had 3 computers on my 360 license.  One lost its hard drive.  I am about to (in mid July) automatically renew the 360 license and I want to have it installed on the same 3 computers, one of which now has the new drive.  How can i do this?  Any advise?
