John,

I can report only on the ease of doing the adjustments, not the =
effectiveness.  I can=E2=80=99t remember the number of turns or the =
thickness of the spacers, but on my 1957 Morgan Plus 4 (a road car) but =
used 20 weight fork oil (Harley Davidson label) since I only wanted to =
affect rebound and not jounce.  It was easy enough to make the changes =
with the shocks out of the car.  It=E2=80=99s hard to say just how much =
of an improvement was caused by the adjustments alone, unfortunately, =
because I found the shocks were low on oil when I decided to rework them =
due to the axle banging on the frame when I drove over every whoop-de-do =
in the road.  One was about 65% full and the other was only 50% full of =
oil and I have to assume that the low oil condition was primarily =
responsible for the lack of damping.  They weren=E2=80=99t visibly =
leaking so I wasn=E2=80=99t able to determine why the car came to me in =
this condition.  At any rate, the car rides like a Morgan that has been =
modified to use tube shocks on the back so I=E2=80=99m happy with the =
overall result.

One caution =E2=80=94 I don=E2=80=99t have any proof of this but I have =
read the opinion that the shocks can be damaged by using oil that is too =
viscous.
