The beauty of chiseling was that often they wouldn't come off clean and
smooth,
which helped in positioning the pneumatic when we glued them back on.

I was taught to drill shallow holes through the pneumatic into the
stack, and put short pieces of steel rod (cut 3d nails worked) into
the holes, so that they could be keyed back into their exact original
position.

wow. ohmygawd, wow. That is so labor intensive. Obviously
it works, but it's a bit more than necessary.

If you use a pencil, you can draw a line across the hinged end. This
shows how far back to have the pneumatic. For left/right, there is always
some marking left on the stack which shows where the pneumatic was.
And the pencil line has a little dip in-between the pneumatics as extra
information.
