There are dozens of threads with correct and incorrect pads information. So far I gathered that the FRONT pad size is 1835 or 1395 ( 189.7 mm wide / 96.6 mm tall).
Which pads did you confirm that fit, both track and daily driver pads. Please share name and model number (rear pads are easier to find).

I’ll start:
Raybestos ST43/ST41 size 1835 available at Portrefield (they cut them)
Power Stop Z26-1835.
