When i picked up my 5v5 last year a very nice experienced rv's showd me and my wife the basics on how to deploy and wind up oour awning. One of his notes was on how not to lose the spring from the awning sabilizer locks.
well during my last week of camping in colorado for elk ( got a nice one), a sudden snow storm came and in my hurry to get the awning down i sent that spring into the dirt and never did find it.
now that its spring the plasic lock pieces have grown feet and are hinding from me.
it this a dealer order item only or do you find these with a trip to say camping world?
ours has two riveted on clips that fold out of the way.
i also use 2" velcro wrapped around each awing arm.
i am not sure what plastic locks you are refereing
but if its an ae awning, go to dometics website and search there, they make em
