Increasing max view angle in IVA for RPM cockpits

[ThatHomelessGuy]

Raster Prop Monitor is great but the camera position is too high to look down at some screens in IVA. When you zoom in on a display to read it more clearly or adjust the display settings it cuts off most of the bottom of lower screens if not the entire screen itself. 

I'm trying to change the cameras vertical view angle range to be able to look down more but can't find anything in the parts files for those cockpits that relates to max view angle. I know I did it in the past for older versions of KSP but its either been so long I've forgotten or how those settings are handled has been removed, moved or changed in the part cfg. 

Does anyone know of how to do this? And if so could you tell me what to add/change and where. I have a feeling it's just a case of adding a vertical view angle variable somewhere.

Thanks in advance.
