Thanks for all the suggestions and tips, you have all been very helpful. I will look at the suppliers mentioned.
In response to some of the questions raised, I have no idea how it was rigged, it will involve some brainstorming and shoulder-tapping of more experienced sailors I imagine. (I spent most of my sailing time on tall ships after my original certification
on 'smaller' boats, so it feels like I'm relearning my sailing skills...
As for the mounts, they are still intact. The deck does have a some flex to it (no more than expected given its age), but it's possible that was the reason it was removed. If that's the case, I may think about trying some sort of a double mainsheet and do without the traveller all together.
The boat is in Toronto, I'm looking forward to getting to work on it this spring! It's great to hear that you enjoyed sailing your Hughes 35 svquintana. I may take you up on your offer of advice once the work on her starts in earnest.
Thanks for all your help, I'll try and post back with any success/failures!
