    I just pulled my 203 and was wondering what I need to look for when I pull it apart, and if they make any affordable rebuild kits. I'm also looking for a cheap shaft part time kit, if anyone knows a vendor who has one under the summit price (300- the only one I could find) please let me know. Any tips or hints are also greatly appreciated /forums/images/graemlins/thumb.gif

    Check out Summit racing part #'s MMK-501 and MMK-502. The first is a part time kit for the 203 the second is the same but includes hubs too. I dont't know about an overhaul kit. /forums/images/graemlins/usaflag.gif

    I know to check the chain to see if it's stretched, and check the gears, is there much else to do?

    Oh yeah, BTW the MMK 501 and 502 kits use the little tabs that go in the diff. in the case, which usually end up wearing out and putting play in the driveline ( I plan on a 6" lift and 35 or 36s). If I can't find a shaft kit for like 150-200 then I'll probably end up using tabs or changing over to a 205... who knows /forums/images/graemlins/ears.gif
