258 Expansion plug replacement

[JZLAJeep]

Have the day off for Columbus day and decided to take on the leaking expansion club on the CJ-7. Bought Dorman expansion plug part number 567-017 which appears to have the "large" expansion plugs, but not the "small" plug that is leaking. I understand that I hit the top or bottom of the big plugs to turn them sideways and then pull them out with pliers, but how are these "small" plugs removed? And what do I replace them with?

Removal is usually done by drilling a hole in the plug and inserting a lag screw or similar into the drilled hole. 
 

Any decent auto machine shop can set you up with a replacement plug if you give them the ID of the hole in the block.
