Thanks for posting. I thought I had seen this before and I was right! After a little digging, I found an old thread from last year where another customer was looking for the same thing. You can view it here. As you can see, Dave mentioned that yours is no longer made and agrees with you that the 81-022 is the closest replacement we have. However, the differences are considerable and there's no guarantee.

Our good friend from California also mentions the 81-258, which is a possibility. Either way, you may not be able to get away without some kind of adaptation to your door. Look over these options and let me know what you think!
