Sorry to jump in a bit late, when i doubled the size of my anchor i swapped my Cheetah for a Jaguar.. it did not fit the exact same foot print but fits the area nicely. i actually have the original Cheetah with little use and none for 15 years, 24v (which made it hard to sell to most cruisers here in SE Asia. i would have offered it to you but the shipping would be more than the value.
i have also replaced the motor and shaft of my Jaguar, rebuilt the old parts for spares, it is easy to essentially have a new windlass in the old housing, if you are upgrading i suggest going up the the Jaguar, mine has been anchoring steadily for 15 years, quite a bit more umph than the original.
