Jollis-ke55

Hey guys I'm pretty new to all this stuff but I am keen on doing a 2TG engine conversion in my KE55. What I need to know is when I go to mount the gearbox, does it need special mounts made up or just be modified? also as far as i'm aware the actual engine is reasonably easy to put on requires slight mods. please correct me if I'm worng. any help would gladly be appreciated cheers guys Jerry.
