I would, since I have a few of the gear drive saws that are complete here. The gear drive is a pretty basic planetary gear set over the clutch, but they take gear oil and it is beleived that most were neglected and wore out, or, since converting to direct drive was so simple, some may have been set aside when a user wanted to use the higher blade RPM.
I just restored an XL-500 and had color matches made in the red, white and green. Those are the same colors of the XLAO-GD, and yours would be a great canidate for me to restore using one of my gear drive clutches.
