I have a leaking cracked "lower" oil pan (part no. 1130101028)... im looking to replace it with a used one if possible, but am not having very good luck locating my particular part no. used.... However, I have come across a couple sites that claim that it is interchangeable with oil pans from the sl55 amg motor (part no. 1130141103) Anybody have any insight on this? thanks.
