Hi All!
Looking at the SLS website this morning, I noticed that they show a "1mm shim, item #27" and a "distance piece, item #26" as part of the setup. See attached pic. I assume that these pieces sit between the plate and the mount? Is this correct?
How important are these 2 pieces? I recently had my trans plate off while replacing my speedo cable and my plate sits right up against the transmission mount, no spacers inbetween...
Thanks for your input on this.
Bob

My guess is that these pieces are used only if required in order to bring the drive shaft flex joint into proper alignment. My set up with the ZF 5 Speed originally had the two pieces illustrated. When I did my restoration work, I replaced both of them as originally installed. I went through the flex disc in about 1500 miles. When re-installing a new flex disc I initially installed both pieces but noticed that the flex disc was slightly distorted. I assumed that this distortion was what led to the early destruction of the previous disc so I removed the shim to relieve some of the distortion. So far so good after about 2000 miles or so. Hopefully others will chime in on this.

Hi George,
How do you see the flex disk is distorted? Can you describe what the distortion looks like?
Thanks,
Bob

Bob,
When I put the bottom plate back on with the shims installed as orginal, wile looking up, I could see that the rubber flex disc was quite distorted and not lying flat. I'm assuming that the stress of this distortion is what caused the first disc to fail after a relatively short perod of time.
