Assuming you mean breakers that retrofit into a glass fuse fusebox, don't the Dorman units self-reset? P/N 84686 (15A)? Or are you referring to standalone units? Its been a while but I'm pretty sure the Dorman's we used to sell at the parts store were automatic reset units.
If the former, then Rock Auto has them, and the "Help!" line the Dorman units are part of may be available at quite a few retail locations. They also list blade type breakers for later fuse boxes.
