Thanks for the pictures!
We do have a different style ratchet option for your older tow dolly but you will need to measure the size of the bracket on your current ratchet.
The most likely option we have is the Replacement Left Side Ratchet Winch # DM5432 or the Right side # DM5433. The mounting plate on these winches measures 2-3/4" wide x 4-3/4" tall as shown in the included diagram.
If this will work for you then I also recommend picking up two of the replacement 3-point Tie-Down Strap... view full answer...
