Rubber door sill, left | 251 863 735

Rubber step, left | 251 863 735

This rubber mat goes under the door on the left side and ensures your feet don't have direct contact with the metal when stepping in or out. With OEM number 251 863 735, you can be sure you have exactly the right part for your T3. The rubber hardens after fifty years, so replacement is usually necessary if you still have the original one. Combine this with the right step for a complete set.
