Thanks for posting! We sell the complete Slimfold guide pin, the 21-007. The cap it uses is our 21-105 and the spring is the 21-251, if you wanted them separately. The bottom threaded pin that matches it is our 21-001 and the cap that part uses is the 21-106. See our video on the right side of this page for more insight, and please let me know if you have any other questions or would like me to clarify anything.
