Rail (750Wh) Magura 220 mm Caliper adaptors

[Bam104]

Could someone help me with making sure I have the correct adaptor and bolts
2022 Rail 9.8 xt - xt Calipers and rotors (203mm)
Upgrading to Magura 220 mm rotors
Purchased Magura adaptor for frame Q45?
and Q40 for the Zeb fork
The Q45 just doesnt seem correct. Existing bolts to attach caliper to long and it seem like the rotor needs more clearance.

Is the Q45 correct? What is the post length on the frame. Prior research I did showed that they were 180mm.

If you haven't confirmed already...
The frame is 180mm direct mount so the Q45 is the "correct" adaptor for adding a 220mm rotor (BTW - Trek states the rear rotor max is 203mm). The original screws supplied with the Shimano adaptor for 203mm are too long for what you're attempting to make work. Since they are not compatible with the Q45 adaptor, you'll want to source some original caliper direct mount screws. If they're from Shimano, they should look like these:
