I just went through this and found that yes, Home Depot still sells the Exide 24f but no 'feet', or lips, for our installation. I visited all the HD
around me and the Exide 24f (variant) is available, but no feet. All the Pep Boys near me carry the 24f Bosch but, no feet on them, either. I did find a proper Interstate 24F, correct post orientation and with feet, at NTB.
I also have a cracked up old Sta-Ful case from which I cut off the feet for future installation on some new battery when the 'feeted'
batteries are no longer around. Hopefully by then the 'proper' Autolite Sta-Ful battery(s) will be reproduced. Not holding my breath, though :-)
