Daily driving an A-body

The best daily driver for snow and ice that I have owned was a 75 Duster, 318 2 barrel with 3 speed manual. This was back in the late 80's early 90's, when nobody wanted a duster, it was kind of beat up but would be considered restorable today. It had the normal rear end sag, tried shackles, all they did was flatten the springs, ended up putting 15's on the back and 4 wheel drive shocks. THe day I bought it was 36 degrees below zero and the heater didn't work(about 70 mile drive)put a new tank heater on it and then it would heat up to where I would be down to a t-shirt in 0 degree weather.
