My 94 GT blew a head gasket ontrack.. My brother drove out 6 hours to get me with a Uhaul tow dolly... It was impossible to fit the car on the dolly. Not only was the rear too wide to fit on (And I only had 275's out back, nothing wide) and even if it'd fit on, it wouldn't have sat in the wheel "pockets" design to hold it on without removing the exhaust tips. There was no way it would have fit on facing fowards either, even if I had removed the driveshaft. I had to wind up leaving it there for a week till I could get back down there with a Auto-Transport trailer. What a pain.
Cliffnotes: Lowered (1 1/2 inches) Mustang will not fit on Uhaul tow dolly in my experience.
