The holes at the bottom are for support pins/screws. You can use a steel pin or a screw to add durability This part is designed the way that once you have taken out the old one out of the gearbox, you can insert the new one without gearbox disassembly Feel free to test it and comment If the design was helpful, you can support me with a coffee https://www.buymeacoffee.com/sunnyfpv
