like someone said call passon. great people to deal with and he'll go over anything and everything you wanna go over. it isn't too hard to rebuild these either. i see you're overseas so maybe e-mail him if its crazy money to call . i've rebuilt my 23 spline and my dad's 18 spline. just get a factory service manual and look up the mopar muscle issue with it in there. basically it sounds like you need somehting new in there and you might as well replace most of it. good luck
