    I noticed the shifter on my 205 keeps coming loose. Last Ime I tightened it, I made sure and greased it, so that the shifter would be less likely to bind up on the bolt, and perhaps loosen it up. Is there supposed to be a washer between the shift lever and the adapter? (where the bolt threads in) I'm thinking perhaps that washer isn't supposed to be there, so the bolt can bottom out and thus be tightened. As it is now, I can't tighten it too much, or I can't move the shift lever.

    How is everyone elses set up?

    I don't think that washer belongs there. You should be able to tighten the shoulder bolt all the way. Is there a lock washer on the shoulder bolt, or could you add one to make up the space?

    It's been a long time since I had mine apart, but the only washer that I remember is the wave spring washer that keeps the shifter from rattling. The threads on the shoulder bolt should bottom out in the hole it screws into. When fully tightened, my shifter still moves easily.

    I don't know about the 400/205 or manual/205 versions, but the 350/205 adaptor needs to have the washer there (the shoulder actually goes through it). This keeps the rattle down but also allows it to turn. On the 350 adapter (not sure about the others) clean and loc-tite the threaded portion of the shoulder bolt and receiving threads and then grease the zerk fitting to lube the shifter itself once installed.

    Here's what GM has to say about the proper linkage configuration: <a target="_blank" href=http://community.webshots.com/photo/16047413/22009229QtoUptGYZQ>1973-78 Transfer Case Controls (Part Time)</a>.

    The "Special" washer, item #13 in the picture, is special because it's a wierd ID/OD combo. Item #14 is the spring washer.

    Hope this helps,

    BTW, if anyone knows where to get some of those spring washers, please let me know. I have been looking for these for a while.

    Thanks,
