They will work if there is a lip for them to hook to on the back of your trailer.
If they will work, take these lengths of wood with you
"2x8" Take a 6" length, a 16" length and a 24" length what ever length, take a pair, you need one for each ramp.
This is in case the car is low enough the bumper scrubs on the ramps, the pieces of wood are to prevent that.
IE.. my focus is low to the ground, IT REQUIRES the PIECES OF WOOD I take to get it so the ramps don't rip the front bumper off.
