ISO 3/8" Corner Key

Hello! I am in need of at least 40 unique corner keys, pics included...i believe this to be a Left AND Right corner key...dimensions
Length: 2 1/8" (flange = 1 1/8") depthh 3/8" width of portion inserted into framing = 1/2" Hope this helps! It is supposed to have the pull tabs but I can manage without them, just need the flange portion to line up and not sure if it is visible from the picture but the flange isn't centered on the key...so it's a bit tricky. Any help is greatly appreciated!
