Thanks for the suggestions and offers of help fellas! Hopefully have gotten it sorted. Popped by Mag & Turbo and they found me some bolts that are just a few mm longer, at $5/each. Silver in colour but I can live with that. I count 7.5 turns now. Booked in to get those checked over and get tag put on this Friday. Hopefully that's the last of the hassle 🤞
