    Ok, the whole 'this 205 fits that trans with this adapter' and all off the different applications are lost on me. Never paid that much attention, I guess. Anyway, here is my query-I just got a 205 out of a 73 Chevy truck that was bolted to a TH350. Is fitting this to my 85 T400 the same procedure as fitting my 79 465 version 205? I will assume I still need the 400/205 adapter? Just making sure. Thanks.

    To answer your PM you sent me, there are a few different spline counts on the 205's.

    10 spline fit the 465 trannys.
    27 spline fits the 350, 700R4, and 4L60E trannys.
    32 spline fit the 400, 4L80E, and '81 & newer 465 trannys.

    Thanks. I was a little bleary-eyed when I logged on this morning and accidentally deleted your PM.

    That t-case (205 mated to a 350) can be used and bolted to a 400, BUT you will need the 400/205 adapter, the correct 400 input shaft for the 205, and the case machined to accept the larger bearing used in 400 versions of the 205. You might be able to sell that one and buy the correct one (less hassle) or even arrange a swap with somebody who needs what you have and has what you need.

    This will also help explain what I'm trying to say.
