That's the way it's been done since I can remember. If corrosion is a concern you can use "Lanocote" as a barrier between the parts. You could also use a nylon or rubber washer to increase separation. Since it's the forstay tang, just remove the masthead and bolt through and use a locknut- everything is well within reach. Or check Your masthead casting, there may be two holes that You could push a pin through. Mount a jaw toggle to that and You have an attachment point for the forestay. Just make sure You have a pin that fits snug through the holes on the masthead casting and also fits the Jaw Toggle. If You want I could go out and take a picture of My masthead then email it to You. Part # for Jaw Toggles Scheaffer 93-65 Alex DJT-10 Have fun with Your project! and feel free to ask questions if you think any of this was helpful.

A friend of mine says he always uses stainless steel machine screws and taps the holes into the aluminum mast when mounting hardware. I wondered about corrosion with Stainless and aluminum together. Is there any thread compound to use to help with this? What about pop rivets? Are they strong enough? and would I use aluminum or Stainless rivets? Any comments would be appreciated.
