Another option is to remove(or have a luthier remove) the veneer cap at the bottonm of the heel and drill the hole there for the heel peg. This has the advantage that when you come to sell it again you can have the screw hole filled, the vebeer cap reglued and the instrument is still pristine. Only worth doing on a valuable guitar, however.

I agree with Clinton that straps attached to the headstock SUCK !
