Broken cover to spring mechanism on right hand side?.

I replaced the right tilt window latch but failed to notice the cover of the spring mechanism preventing the window from closing was broken. The clip ended up broken, since the case is designed to gradually move the clip in as it goes over the spring mechanism. When trying to remove it, it slid down the side of the window, due to the spring. One picture that I uploaded is an undamaged part, the second, the damaged one before I took the screws out. The only letters that I can see are G and H, which can be seen in 3rd picture.
