Bear Hunter Take Down riser made wrong

[tsarna]

Hello I have a bear hunter take down made I think in the early 80's well I think the riser was machined wrong with a slight angle where the limbs attach to the riser so it places a angle on the limbs I have tried having bear archery help me out and they say that there was a shim that bear had plaaced under this limb to fix the problem but could not help me out with the part can you help not even black widow will help me out?

Thanks Ted Sarna
