2010 Kodiak hybrid question

I recently sold my class C MH and then purchased a 2010 Kodiak model 184. Have had it out a couple of times and am pleased with it thus far. I have visited this forum a few times for info about the fold down doors and general experiences. One question I would like to know if anyone has the answer to is regarding a part that is on each outer corner of the bunk doors. is a plastic socket that the tent hoops snap into. I'm concerned that these will not last and would like to obtain a spare or two. I've contacted the manufacturer of the door (Challenger Door) but they don't make that piece. I'm also in contact with a dealer put they are indicating this might be part of a tent hardware kit. Is anyone familiar with this part and know where one might get spare ones from? I'd include a picture if I knew how. Thanks, Mark
