There was a recent thread that briefly discussed this. http://www.huntingnet.com/forum/tm.aspx?m=1214158

You might find some help there. Also, you can find the conversion kits on GFK's website : http://www.goldenkeyarchery.com/dropaway.html

If you scroll down on their page you'll see the drop away conversion kit FAC-1 for $24.99. This is the kit that I purchased for my Infiniti rest but it will work for any of the Premier series of rests.
