yeah that is what i posted just above you. i have a machinist buddy that can make me a d44 spool then broach it for toy splines for free. it would be made of 4340 cromo. also, if i get an arb and take it apart he can make the part i would need with custom side gears out of 4140 or 4340..... i think i am going to start cutting and see where it gets me.
