Towing with an A body

Hey-

I was told not to tow without an 8 3/4 rear end, but I'm trying to figure it out- I get the car back tomorrow and I can check then. The hitch I have on the AS does have sway bars, and it does make a huge difference towing. I was thinking that the disc brakes would be smart- we have lots of hills here. The drums aren't as scary as I thought they'd be tho...

thanks

Peter
