Stop in for a cup of coffee
so decision time on the brakes for the polara.
Stay with the drum brakes and fully rebuild them, shoes, drums, bearings, hardware, master cylinder, hoses, lines etc.
Upgrade to A body disc brakes, for which I'd need the spindles, rotors, calibers and pads. Already have the shields, caliber brackets, old calibers, new hoses, lines and master cylinder.
cost for drum rebuild: 370 bucks
cost for disc brake conversion: 300-400 bucks
