Advice for long arrow quiver

[LoweBow]

I'm shooting full lenght (32") 5575 GT shafts thru my SXT 60" Zipper.  The Kanati limb bolt quiver I'm using leaves my knocks sticking down past my limb tip about an inch.  It really sux as when I try to lean my bow against a tree and it wants to sit on my knocks and not the limb tip.  Any suggestions that will place the hood up higher and more center my arrows on the bow?
