New Cams for Old Bow

[pjsrider]

Howdy all,
I'm new to the archery world and just recently purchased a Martin Lynx magnum bow. The draw length is currently at 31" I need it to be around 29". Can I change the length with just adjustments, or do I need to get new modules for it? The bow is still in shipment, so I have no good pictures of it. All I have is the picture that was with the ad on ebay. Any information would be great. If I need to get new cams, can I retrofit ones off a newer bow?

Thanks,
Jay

I don't think the Lynx has flight wheels (rounder wheels with notches to modify the draw length)
I would think you will have to change the modules to change the draw length.

Changing to a new cam is not an option - if that's what you want to do, it would be far easier/safer/cheaper to buy a more modern bow.
