Need to find new crank operators and possibly a track

Hello,

We do not carry an exact replacement for your old style operator but there is a chance that our 39-365 operator, along with our 39-114L handle, may work as replacements. We also offer the 39-366 opposite-handed version. Both operators are compatible with the 3-520 track. We can't make any guarantees but review the measurements below to see what you think. Thanks for posting!
