🛠️ Important Fitment Note – For Use with 16mm Girdles:

🔧 Sump modification is required when used with 16mm main girdles.
The rear four main stud nuts will typically contact the sump floor.
To address this, we:

• Drill clearance holes

• Welding in alloy cups (This modification ensures correct fitment and oil-tight sealing.)
