Gary,
The original shocks on the Dragonfly were early series Girling units that had very soft damping. Later units have too much damping and ruin the smooth ride of the Dragonfly. The original front shocks were 13.9" long with 54 lb springs, and the rears were 12.9" long with the option of 100 or 110 lb springs (depending on the weight of the rider).
Hope this helps,
Regards,
Eddie.
