Hi everyone, I am in need of some serious Lude expertise here

!! I have been surfing the web for answers, but I'm sure someone on here might be able to help. In short, I am in need of an
M2P4 Gearbox, for my 5th Gen, H22A8 BB8 Prelude, manual 2.2 Vti. But is there a suitable replacement or an alternative gearbox I could use…
Any help would be greatly appreciated

Many Thanks
