J/30 Class Association Forums J/30 Forum The Boat, Sails and Equipment Harken spinnaker car track to deck

I understand this may not be allowed for OD, but I'd like to add it.
Has anyone added Harken track to the front of the mast?
The current track has a wide base that is pop-riveted on either side for the full length. I'm concerned that if I pull the standard track off, and then drill new holes every 4" for the harken track up the middle, that the mast will look like swiss cheese and be substantially weakened.
Anyone with any ideas? Maybe the Harken track could be tapped on top of the current track.
