We had problems with both the aluminum bronze plugs and the piloted insertable aluminum plug lw-11775 as well as the one piece pins from eci and superior which had a non removable plug like the lw-11775. So we used the aluminum 60828 plugs. Still would have one go bad occasionally but had the best luck with them.
Pecking order for us was 60828, lw-11775 or equivalent, 72198
Good Luck,
Mahlon
