My question is whether it would be better to fasten the track with SS
rivets dipped in some isolating compound.


The isolating compound you are looking for is ordinary silicone
sealant. It works fine for either rivets or threaded fasteners. It
it were mine I would re-tap the holes and bed the threads with
silicone. Temporarily tape the new track to the mast with duct tape
to line it up and get a couple of widely spaced holes holes
drilled/tapped. The rest should fall into line pretty easily if you
center punch the holes accurately.

If you end up using rivets, these are the ones you want:

For what it's worth, anything over 1/8" diameter will most likely
require a powered puller.
