Milodon stock-style oil pan fits 1965-72 Full size cars including Impala with 2 step design oil pan. Used for Big block 396 402 454 with 2 piece rear main seal. This pan was used for mock up only, it never had oil in it. This is an older 30710 that has been replaced by a generic one size fits all pan.

Call me if you have any questions.
