I don't have any handy to look at, but if you held a stocker and L35 side by side, you can tell the difference pretty easily. More mass around the shoulder area, near the rod bolt section.
L35 rods have a rectangular protrusion on both ends of the rod. On the cap, the rectangle is cut cleanly and is oriented so that its length is perpindicular to the line created between the two rod bolts.
Stock rods have rectangles with rounded corners that are long in the same direction of the line created between the two rod bolts.
