### 1. 🥇 Best Option: **6903 + Shim Sleeve**
- Get a **6903 bearing** (30mm OD)
- Machine or find a **thin steel sleeve/tube** with:
- **ID = 30mm** (fits over bearing)
- **OD = 33.4–33.5mm** (press fits into old race)
- **Wall thickness = 1.75mm**
- Loctite everything together
- Steel tubing or hydraulic pipe cut to 7mm width could work!
