You should not be able to remove the spar pins from the fuselage..
You should only be able to move them out of the spar, and they stay
fixed in front of the spar. On my LS-1f, the spar pins slide out of
the spar, and remain forward of the spar by about two inches.

Email your address and I will send you pictures. I can also measure
the pins when I am out at the gliderport tomorrow.
