Stus-List Genoa track leaking on a '94 37/40+, can't seem to access underside?

Hi Rob,
Yes, I'm sure the track was original, as it is Lewmar equipment and matches everything else on the boat. I was thinking something similar (I was wondering about bedded nuts, but your approach makes a LOT more sense).  

If you look at this photo you can see a "step" where the track is mounted at the bottom of the fixed port before it steps down again to the deck level.  Would this imply such a laminated strip of aluminum?

Would you think when they put in the stainless screws they might have coated the screws with something to prevent dissimilar metal corrosion (crossing my fingers...)?  

Rob, having your insights on this board is amazing.  Thank you for chiming in!
Kindest Regards,
Bruce Whitmore

Was this track installed when the boat was built . . . . ?  I know that occasionally fittings were installed by laminating a strip of aluminum into the laminate – then tapped, so the machine screw didn’t have a nut on the under side.
 
Having lost most of my memory now, I can’t say if this was done on the 37, but it’s a possibility.
 
One can now see one of the possible weaknesses of the system . . . .
