EDIT: I think also you could use two of the four attachment screws/bolts. Take one out, see what thread they are (possibly M4?) and get the required length to fit. Again something I have done.

Thanks for the reply,

Yeah I think it is for friction. I was thinking of using that and two of the other bolts, but wanted to know if anyone HAD actually done it.
