Well the march ST gearbox from what I hear fits the CG13, so on that basis the 1.0 and 1.3 would also fit the K10. I have said this for a while now
I'll go and try it now.....
Ok I dont have a MA10 without a box attached and i cant be bothered to undo it, so I tried a ST box on the CG10. It fits perfectly. What I cannot tell you is if the starter will line up or not. I presume it will..
So people with K10s who keep blowing gearboxes a CG13 box may very well be an option (nice to know since I keep blowing the ST boxes and parts are hard to find..)
