Notes:

1. Professional Installation Is Highly Recommended

2. Please do not buy if your engine with starter bottom mounted since the mounting holes are not same.

3. Please allow the slight color difference caused by the shooting light and 1-3cm error due to manual measurement, and make sure you do not mind before you place the order.
