Hello Larry,
Thanks for writing in.
I see you already figured out that with your original flange being cracked, you’re going to need a new one while you’re swapping out the toilet. It also looks like you ordered both flange options, so you’ve got yourself covered there =)
Which one you’ll need is just going to depend on how your current setup is plumbed. The LaSalle Bristol # 3446336343 has 3" male threads, so this is the one you’ll use if your flange threads down into a female connection. The # 3446336345 has 3" female threads and will thread over a male connection.
Once you get the old toilet and cracked flange out of the way, it should be pretty easy to tell which setup you have. Honestly, having both on hand isn’t a bad thing here. You won’t get halfway through the job, discover you have the other style, and then have to put everything on hold waiting for another flange to show up.
You should be in pretty good shape to get the new Seaflo # SE92MR installed and take care of that cracked flange at the same time. Hopefully this is a quick project so you can get back to enjoying the RV. After you get it figured out, let me know which one you didn't need so I can get you taken care of.
Getting things geared up for a final summer adventure, where are you headed to next?

Larry, when I purchase this toilet for my RV it did come with rubber seal, flange and flange bolts. I used all of the new hardware and it was a straight swap minus have to modify my water line to fit, (prior toilet water connect was higher). Has been a great toiled for full time use.
