Alternatively, why not get your original trolley repaired ? A local welder could probably do the job for a lot less than the cost of buying a new one. I had to modify the launching trolley that came with my boat to fit the road base. After cutting, narrowing and rewelding, I sprayed the heck out of the welded joints with galvanized spray. And, touch wood, no problems yet. A good local welder wil produce joints every bit as strong as a factory produced item. Regards, Davdor.
