Ordering valve parts

I am ordering a new valve body from Airforce tomorrow, so I can send my tank to Tony and have him do some valve work for me. I trashed my old valve body trying to get it off my tank (to no avail,) and I was never able to get my burst disk out. So, should I also order a burst disk from them? Besides the burst disk and the retaining screw, is there anything else that goes in that little hole that I need to order, or am I okay with just the valve body?
Thanks,
Chris
