From Dave Jones

I haven't read the SDR yet, but if it says 3/16", that surprises me, because 
most of the people reporting movement of the walls of the gear case have 
mentioned a 3/8" or more excess in shaft length.

I agree that such a small thickness may let the disc rotate, and it might be 
a real problem.

In my own case, I used a standard plug, EL-6B, if I remember correctly, and 
it was about 5/8 or 3/4 long, and so its placement at the ass end of the 
cylinder presents no problem for dislodging and turning.  It is in my plan to 
remove it and thin it up a bit after I see what effects it has had, but I 
know it will not be thin enough to jump around in the cavity.  I think 3/8 or 
7/16 will be the minimum.

Whether you put it on the ass end of the plunger or slip it over the shaft 
depends on your initial adjustment of your system.  In my case, all the push 
tubes were adjusted in accordance with the manual, which says to completely 
extend the shaft of the cylinder and then drill the attachement hole.  Mine 
need the spacer at the ass end of the cylinder.

In any event, you should check the throw of the newly adjusted cylinder with 
it disconnected to make sure you have it within the swing of the arc of the 
flap bracket.

I have had an email from Lance regarding this, and he says the factory is 
coming out with an official SB and a retrofit kit-maybe the kit will have 
spacers of different thicknesses.
