I agree, the 90-253 is similar but not quite identical. There is a chance it will fit over your existing latch, but I'm personally not optimistic. Figure that the 90-253 is only designed to fit over the 90-252 mechanism. It's not made to fit on anything else, so using it in any other capacity is going to be a gamble. I've personally never used the 90-253 on anything other than the 90-252 mechanism, so I unfortunately can't advise.
Hello! That lock mechanism appears to be the same as shown in the photos above. If you haven't already, I highly recommend reviewing the hardware we've suggested throughout this thread to determine if they will work for you in the same capacity.
