Shoulder - WM Shoulder (only details on part I could find)
scale 1.2
Bi-cept - WM Upper Arm - 3D & Unfolding by Zabana
Scale 1.5
Shoulder seams to fit o.k so I left it as is... Bi-cept required 1.5 scale to fit my arm but was to tall from my shoulder to elbow. I cut the top off about 1.5" down from the top and then pushed the 1.5" top into the sleeve and re-glued it
it seemed to work for me
