sigh.. found a series of posts in comp.sys.perq and Tony and RD Davis (RIP)
were discussing this twenty years ago :-(
where did you find the information about the guard band pattern at the ends?

Then try to insert some small pieces of paper over one

wrong the failing is the left) in place of the missing rubber, and try the
disc, and continue to add thickness until it works.
Then you are sure about the right limit to move.
Then remove the paper, loosen a little the screw, but just a little so the
limit will not move unless pushed with some strength and a screwdriver.
Then move a very small amount towards the center and try, then repeat trial
and error until the disc starts. Then tight the screw and it is over.
Close the disc and voila.
