Nice! I'm fresh out of later stuff. I sold Jeff Campbell my NP205/TH400. I even had a 4L80E/NP241 w/controller from a '91 Suburban diesel I let go. Gotta do what you gotta do. All this talk about later spline count vs old but I've never had a 10 spline 205 fail. I'm also not into rock crawling and running w/o overdrive suits me fine. The original w/TH350 is doing fine in my '72 K2500, I have a 4spd/NP205 all coupled up sitting, four spare 10-splines, one extra 4spd, and one adapter spare.
