A friend of mine has a two post he put his 37 V8 on it however car was too far forward he lifted the boot (trunk) lid and the car tipped forward too much weight at front. Thats why I got a four post easy drive on ok you have too put a jack in too take wheels off but its safer for me.
I use mine at an angle to leave a windrow in the middle, grade both sides like this then turn blade around facing back wards and drop it then run down the drive and it spreads ok normally after rain so not to lose the fines.
