Default [Q] T999L Parts Help?

I need to find a replacement SIM/ SD module (a small part which contains the slots the SIM and SD chips go in) for a Galaxy S3 SGH-T999L. I am not sure whether parts for the T999 would be compatible with the T999L. The part is everywhere for other model numbers, but replacement parts for the T999L seem impossible to find. Is it possibly the same part as the T999? I wouldn't know. I have searched high and low for the answer to this seemingly simple question, and I'm the only person I know of to ever raise this question on the internet, which I think is just funny.

Thanks for any any answers.
