A-Bodies in the snow?
drove my 67 Barracuda all winter long,
don't remember doing anything special one day driving my sisters 67 Barracuda fastback Formula S drove it out into a field because there was less snow, well got it stuck in the mud instead, we were laughing but late for school that day
But that was in 1974
if I had to drive an older car now in the winter on salted road, make sure you wash the under side as often as you can, have heard of people cleaning the underside and coating it with oil
As others have said, SNOW TIRES & SAND TUBES
but best bet is find a FWD car that has some ground clearance, DON'T ADD WEIGHT TO THE TRUNK takes the weight off the drive axles
Good Luck and hope it works out
