If you go to an open driveline consider a mid 80's s10 blazer 4x4 rear end. They are plentiful in the midwest salvage yards and are about the correct tread width. 5 lugs, drum brakes and if you look in the glove box door there is a label that will tell you what ratio it is. I run one in my 37 sedan with steel wheels and baby moons. Looks like the sixtys.
