Can I use a surface pro 6 1807 screen/digitizer as replacement?

I have a surface pro 6 1796. i have replaced the screen before (with this) and it worked fine until the digitizer/control board died, now I am trying to replaced it again (with this other screen) and digitizer. i only have 1096 pressure with this setup and the tilt function causes the screen to think im touching in random spots. THEN, if i run surface diag it breaks the pen pressure, and nothing at all at various angles! what am i doing wrong...
