A 3rd possibility is the upgrade fuse panel sold by Larry Stock's Pantera Parts Connection in Carson City, NV. It is a rework of an original fuse panel including the second small 2-fuse panel for the windows. Both panels use modern blade fuses and is plug and play since it bolts in using OEM screws in the stock position. 6 or so years ago, Larry & I installed one into one of his customer cars; it took us rookies 30 minutes to swap over one wire at a time and at the end, everything worked first try! Quite a few of these stock-appearing systems out there now, with zero problems.
