looking for a hoyt redline cam for my viper bow left hand RL7-L-HO thanks

I have a left-hand Hoyt Redline cam number RL7-L-HL. I need to shorten the draw length of my bow, so I'm looking for an RL4-or-RL5. If I can find one, I won't have any use for the RL7. Keep an eye out for me and we can work something out. Thanks
