Usually you can slide something small and flat into the smaller notch visible on the front side in your posted photo This notch lets you compress a tab that sticks out of the brass part which is holding it in the black plastic
After removing it You might have to bend the brass tab back up a bit before reinserting because they aren’t exactly great springs
I usually use a very tiny screwdriver for this task
If you aren’t sure of the process try on a junk one first from the wreckers to get a feel for it -s
My '50 Chevy 3100 5 window, '62-235cu, 3:55 rear My truck ....... Respect The Rust If I'm not working on my truck, '65 m00stang or VW camper, I'm fishing with the wife or smoking Salmon.
I ended up using a piece of trapping wire flattened on the anvil, worked alright, although a tiny screwdriver like suggested would be better. Thanks guys!
High Plains yer larnin from them "bolters". Seriously get,or make as was said a tool to trip those little brass triggers thru that little slot,once out adjust so it snaps back in. Can then put in a fresh clean one with no corrosion.
