I am considering changing over to F body rear springs on my GN but I would still like to run air bags. I know the F body springs are smaller diameter and I am curious if anyone has used the airbags made for f body's in a g body using f body springs? I have an antiroll bar in my car so the airbags are strictly for supporting extra weight in the rear when the trunk is full and 2 back seat riders on the Power Tour and events like that.
