New limbs for 2002 Panther Fusion Cam?

[Gray2Hairs]

I have a 2002 Martin Panther Magnum with Fusion Cam 60# limbs and 65% let-off. I would like to replace the limbs with 50# limbs and change the let-off to 75%.

Where would one go to buy limbs? If changing the let-off is difficult or fairly costly it can stay at 65%. What is required to change the let-off? Can parts for this old bow still be had?

Thanks.

often find martin limbs on Archery Talk classified Ads, both the 17'' elite and 13 and 14'' . not sure about let off but it does have something to do with different modules.

I received some info about the let-off and draw modules. Evidently the module I am using (F-4) has 2 versions. The 75% or high let-off module is F-4 while the 65% let-off is marked F-4/

It appears that a module change is what is needed to change the let-off.
