Any Repairman can Mark. They work and use all the pins and inserts.
Uniloc insert is no different if you are having joint issues. If you are looking for a Predator Repairman. Ryan at Mueller's is one.
Is the shaft offset a bit? Like maybe not installed center.
I wanted to mate another thinner diameter shaft to it.
This is his second post.
Thinner diameter, meaning diameter of tip or making the joint collar fit properly.
If it is a thinner joint collar on the shaft than on the butt, no way. If it is wider, then yes, you can have it mated to the butt.
Me don't know what he meant tho.
