I am buying a '56 Packard that is on flats (been sitting for ages), I need to figure out what other rims fit so I can bring along some rollers when I move it. It is a Senior Packard (not a Clipper). My interchange manual shows 15x6 5-5" bolt pattern. This is the same as 50s/60s Cadillac which I have extra rims of. Anyone know if I can make these work, or what rims I can use, just to get it rolling? Thanks
