Devin, Since some of the largest production sailboat builders in the US are in the southeast... and they all have contracts for many different length handrails with their SS fab shops (either in house or sub contract)...
Figure out what length and loop spacing you prefer and could live with, and give 'em a call.
i.e. You might want to consider "going over to the dark side" (as an owner here used to call it) and putting on SS rails.
What with the hassle of refinishing teak regularly, I know that if we ever break a rail, we WILL replace both with SS!
And then, with a 30 year old boat, you are probably going to have to epoxy in the old holes and redrill/overdrill/epoxy-fill/final drill again for each hole anyway. Some spot gel coat refinishing of the cabin top will be in order, no matter what.
Jus' sometin' to consider...
