We're looking for a seal kit to rebuild the shock strut on our 2 place
lark
if anyone knows where parts can be found. I understand the Blanik also has
the same strut.

There's nothing exotic about O-rings. They are commonly available in metric
sizes everywhere. Consulting with the local supplier may result in a
recommendation for a better rubber compound than the original.

A nice solution is to try to get another strut from a crashed Lark and
rebuild it first. Then swap it for the one in the glider to minimize
downtime. Get a generic shop manual for re-building hydraulic cylinders -
the techniques are the same. Re-build the old strut in your spare time so
it's ready for the next time you need one. The toughest part is going to be
getting the strut out of the glider.

One more thing. I am convinced that the struts are damaged if allowed to go
flat. Topping off the strut with nitrogen on a monthly basis seems to make
them last much longer.
