    You would want a '205 that came off a TH350 (i.e. is 27 spline)... most '205's are from SM465's (10 spline) or TH400's (32 spline).

    You'll also need the adapter, the "foot", that goes between them. Drive shafts will likely change, as a '205 is shorter than a '203.

    You know, for all that work, you're halfway to a Doubler: get a TH400 version 205 (more common than a TH350 version, methinks) and a Doubler from NWF or ORD or whoever, plus all the above, and you're golden.

    i'm pretty sure all TH400s are 32 spline. and a TH350 is 27 spline (that's what i have).

    Daggum it, I always get the counts wrong. :doah: I'll edit my post above.

    So, ignoring my details which I got wrong :D the basic point remains -- you're halfway to a Doubler! :deal:

    yep dremu has a good point, if you're going to have everything apart right now, you might as well just take it apart once.
