I am planning to tow my 48 DeSoto to Moyer Automotive so they can install new brake lines, fuel line, new exhaust system, driveshaft, etc. on a lift. I went to U-haul to get a car transport to haul my car there. But they said there is no winch on the car trailer to haul the car up the ramps. I've rented car transports in the past and they seemed to have winches in the past, but not now. So I'm going to buy a Come-a-long winch at Harbor Freight. Should I buy two Come-a-longs, or would just one be enough? Should I buy the 2 ton or the 4 ton Come-a-long? And is towing with a tow dolly a bad idea with the drive shaft installed. My car has fluid drive. Thanks.
