Trick flow noob ?s

Can you buy replacement bushings for this PRW’s?
The reason I brought this up is because if you look at the CC rockers you have, you will notice they have a split bush in them, which is not honed, instead of the solid pressed in and honed ones most rockers have.
This to me looks like a steel backed type bush that's designed to be easily replaced, (like a transmission bush).
When I asked Comp about getting replacements, they told me that even though they are easy to replace, they don't sell them. You have to buy another rocker..
