Shorlander Keel Rollers

Hi, I have a Shorelander trailer that I need to replace the 4 front keel rollers. They are 5/8″ pins and they have some triangle shaped keepers on the ends of the pins. I would assume that they will pry off in order to get the pin out.
Do the triangle keepers pry off ?

they look like this

If they are aluminum like the ones in the link, you’d have a good chance of opening them up. At $.60/ea, I also would be opposed to having a few extras in case you mangle one or two getting them off.
