Question Changing freeze/welch plugs without removing engine

Even though there is only 20k on the rebuild, the welch plugs on both sides of the block are corroded and weeping. Anyone have techniques or tools that could make putting in the new brass plugs easier? This on a 74 Scout 345.

So has anyone tried the OTC Frost plug tool?

I just used one of those seal installer deals with the removable cups. I put on the smallest cup in the kit and it drove the plugs in evenly. The tool I used was similar to this: https://www.napaonline.com/en/p/SER41630

Hope this helps

Thanks.
