Camera pressing on the screen after a housing swap

I recently bought a new housing for my iPhone 6 similar tothis, which makes the iPhone 6 look like an iPhone 8, as my phone was bent and I figured it would be a bit sturdier. After I transferred all the parts over, I noticed that when I put the screen back on, the camera presses on the LCD and makes pressure marks. This is because the new housing has a larger camera lens to mimic the 8, and mounts the camera slightly lower on the case to do so, making the camera touch the top of the display. The listing for the housing has a guide for the camera installation, which I followed, but and not having any luck in doing. I've tried installing the camera with and without the camera bracket, I've used paper spacers to try to press it in place, and I've even removed the metal shielding on the camera to try to lower the height with no luck. Do you guys have any ideas on what else I can do to make everything fit?
