Mounting a GB handle on a Kris Hom seat

[siafirede]

How do I go about putting the GB handle on my Kris Holm seat. Do I take off the foam and everything? If so, what is the best way to do this, can someone give me some instructions? I just dont want to destroy my saddle doing something wrong.

Thanks.
