NB2 ECU case dimensions?

Hey guys. Im currently overseas on vacation in Vietnam and I have a lot of extra time on my hands.

I have a rusEFI STM32 MCU on a SpeedyEFI adapter board. Car runs good sans a trigger error that hopefully will be fixed soon. I am currently designing a way for the speeduino hardware to bolt into the stock ECU case cleanly. I managed to get the dimensions of the stock ECU, the Speedy adapter board, and the rus STM32. I have made models of each of these already.

Upon positioning them in SW, i have realised that the way i want to mount the ECU will require a spacer installed onto the "cup" part of the ecu case to extend it heightwise as the speedy is taller. Does anyone have a stock ECU case that they can measure for me as I dont have any of the actual hardware with me here?

I will be linking the models and datasheets on gdrive if any PNP guys want to make their own board. Theyll probably move but ill keep the link updated

Thanks for the help, MP
