Not something I would recommend!
When using either a "Z" bend or a clevis and you do not want to replace the control horn you could use the wire from a twist tie and drill a small hole close to the base of the control horn. Fit the twist tie wire through the hole as wrap one end around the end of the pushrod/clevis a few turns. Then pull the wire to remove any slack and then wrap the loose end around the pushrod/clevis a few turns also.
Trim the loose ends and now the pushrod cannot pull out unless the whole control horn rips in half.
If you are using linkage stoppers I would use a small piece of a coke can which is folded to fit over the broken end of the control horn. Drill a hole straight through the AL piece in line with the hole in the control horn. Fit the linkage stopper through the AL piece when fitted over the control horn and then drill another hole through the Al and Control horn closer to the edge opposite the linkage stopper. Apply a drop of CA and again using the wire from a twist tie secure the AL piece to the control horn and CA to secure.
Have fun!
