General Information
The original version of the ubiquitous "death stem" as identified by having two slots for the expander bolt on each side, this combined wit the quality of the casting was the cause of failure at the top of the expander section as shown in photos.
Later version of the stem was significantly safer with a different casting and 1 expander slot on the front face of the stem, where most riding stress would occur.
