Which is the OEM Bellows Ring - HELP!

[AMMO DAWG]

I screwed up and could use a little help from the experts. I bought an OEM Drive Shaft Bellows and it came with an OEM ring. I also bought an aftermarket engine alignment tool set which also came with a ring. Not paying attention I threw them in the same box and now I don't know which is which and I want to install the OEM ring with the OEM bellows. I attached pictures of both rings, neither has any markings on them. Let me know if you have any idea which is the OEM ring, the short one or the tall one. Also, I'm having a hard time keeping the bottom of the bellows in the groove, seems like it keeps popping up, is this typical and any suggestions to make sure I seat it in the groove when I install the ring, thanks in advance

The large O Ring goes in front of the bellies, seals the outdrive
