Hi, guys.
I am a newbie at archery. Just target shooting with my two grown sons. I picked up this used set up and took it to Fin, Feather, Fur to have the draw length shortened. They were very helpful but said that I need to replace something to adjust the draw. The one wheel has a "7" on it. Reading through some of the other posts, I have learned enough to get myself into trouble. The draw now is about 30" and I would like it to be about 28". What number wheels do I need and can I still get them? Can I change them myself? What year is this bow?Name: martin bow 001 (800x599) (800x599).jpg Views: 355 Size: 55.9 KBName: martin bow 002 (800x599).jpg Views: 327 Size: 31.9 KBName: martin bow 006 (599x800).jpg Views: 319 Size: 27.4 KB

Thanks for any info you can pass my way. Sorry about not including all that technical stuff, but I don't know what any of it means.
