I drained the fluid out of my 208 last week and got these nice little bearing pieces that came out with the fluid. This is in the '85 K5 with the SM465. What can I put back in there without doing major modifications? I.E. what spline count, long shaft or short shaft, etc... I'm not doing any major 4 wheeling so I'm not opposed to another 208. The other question I have is whether I should just rebuild the case I have. I don't know what's wrong with it other than the bearing pieces that came out with the fluid change. It still shifts fine and as far as I can tell the 4x4 works. Thanks for your suggestions.
