Hi, I was wondering if there’s any possibility of cross compatibility between i7378 and i7359 from dell? My computer is the i7359 but I haven’t been able to find a reasonably priced replacement display. Thank you very much! Also, I found this alternate guide suggesting that the screen can be replaced slightly more easily than the manual and this guide suggests, is this process feasible? https://www.insidemylaptop.com/replacing
