Fitting Matchmaker X to SRAM Guide T brakes? I've got a prebuilt MTB that came with an SRAM NX drivetrain and Guide T brakes and I'm looking at upgrading the drivetrain to higher end parts.
I'm thinking about taking the upgrade opportunity to switch to the Matchmaker X system, the new shifter will definitely be compatible and I can get hold of a clamp like this without an issue:

I understand that the new shifter will be attached to the screw thread facing downwards. The SRAM website claims my Guide T brakes are Matchmaker compatible too (https://www.sram.com/en/sram/models/db-gde-t-a1) but it doesn't look like it from their picture as its a two bolt clip similar to this image. My brake body has half the clamp molded into it, then the second piece fits on the back.

The Guide R below appears to be attached through Matchmaker, but the body is a completely different shape below. It appears to have a small wedge with a hole for the Matchmaker clip's bolt to fit through

I'm either missing something silly, or are there are multiple versions of Guide T brakes with different body styles that SRAM doesn't make clear on their site?
Further research shows there are two systems, Matchmaker and Matchmaker X. My Guide T brakes allow the use of Matchmaker and the new Eagle Shifters use Matchmaker X. It seems as though all of the other Guide brakes (including the R the bottom picture above) use Matchmaker X.
I either need to find a Matchmaker clamp adapter like this https://www.sram.com/en/sram/models/db-acc-mm-a1 (which I'm unable to find in Europe), or swap my brakes at the same time.
