Silly Bro Caps. Where there's a will, there's a way. And I am a large Will. (sorry for ****ty phone quality...couldn't get it to focus on the stem or cap)
*Note: I do not recommend this method. I could not wait to try and find a topre version of the cap, and ended up mutilating one of the MX compatible sliders I bought. The cap sits a bit higher than normal, but other than that, sits completely fine on the switch.
P.S.- WTT Sifo's soul MX for Topre
