Battery, USB-C port and camera assemblies each have exact-model guides; the larger Pro Max is not a parts match for the 17 Pro.
What to check before buying
Battery work
iFixit documents a battery replacement for the Pro Max rather than applying the smaller Pro procedure. The larger Pro Max uses its own battery part and opening procedure.
Other assemblies
The USB-C port, front and rear cameras, LiDAR module and loudspeaker have separate procedures. Use Pro Max parts and instructions for this larger chassis.
