seat back removal

[Tunitime]

I have a Maxum SCR 3500 and would like to take off the 'L' portion of the back seat (or whatever this is called) per the attached picture. Problem is I can't figure out how it comes off. The 2 little silver studs is my problem. Any help is appreciated.

I appreciate all that reviewed my question. I am happy to report I found the answer to removing the L shape back. The back panel that jets out from the wall pops off the rest of the upholstery. As you can see there's no seams, therefore it pops off by pulling straight out. It is attached by those little plastic insert thingies. Now I see the hardware to loosen and bingo, it's removed.
Thank you for trying to help.

I will post pictures early next week when I put the seats back in. Thanks for the suggestion.

I finished my project of removing the seatback from my 3500scr. It was suggested I post some pictures...but first I must say I found screws that were cut from a previous owner which helped me remove the seat back. I guess 'hook & loop' velcro was not invented yet (lol). Anyway I installed using existing z clamps and 'hook & loop' where needed. The back panel pulled right off the frame. It was installed using plastic push pins of some sort. Then I removed screws from pipe and one screw hidden in box screwed down to fiberglass wall. Presto...lift right up.
