You must achieve a positive STOP at both the fully retracted and fully extended positions in order to remove stress at the cylinder attach points.

Do whatever is necessary to obtain this result.

In the retracted position, a spacer or washers on the shaft will work but a single spacer of the correct length is best. If a shaft turns out to be too

long in the extended position, you can shorten the throw by adding a spacer on the shaft INTERNALLY.

In this pic you can see the internal spacer I used to shorten the throw of my nose gear cylinder.

Hope this helps.
