Greetings. My rear suspension is very bouncy, and I=E2=80=99m sure I =
need to have the lever-arm Armstrong units rebuilt. In the meantime, =
I=E2=80=99ve also been looking into period-type improvements. I=E2=80=99ve=
 read that the rally cars used DAS10 (instead of the stock DAS9), but =
these require chassis modifications in order to work. I=E2=80=99ve also =
read there there=E2=80=99s a twin-valve version of the DAS9 (as opposed =
to the stock single-valve) that=E2=80=99s supposed to be more =
adjustable. Does anyone have any information on these, like a part =
number that might help me find a set?

Thanks.

The stock valve can be adjusted both ways, by changing springs.

My suggestion would be to send them off to Peter Caldwell for rebuilding

And ask for stiffer valving (if he doesn't talk you out of it).  The stock ride is plenty darn stiff, yours is only bouncy because
the shocks aren't doing anything.
