Where to mount a rear peep sight?

[TG509hunter]

Looking for some advice on where to mount my new williams peep sight on my traditions muzzleloader.  Where do you guys have yours mounted?  I wasn't sure if I should mount it where the iron sights were, or on the front or rear portion of the scope mount.  Again, any advice or pictures would be greatly appreciated.  I'm not hunting the early season so I have time to play with it.  Thanks again!

I put mine as far to the rear as I can...
