Almos any maker that has a deep - front sump as long as it is no wider than the space between the frame mounts.
milodon and the pickup that goes with it. should fit through the crossmember without a problem (in theory, since we haven't installed the motor yet)
I've used both a Milodon and a generic e-bay pan. Although both worked, it was easier to install the motor with the Milodon pan. It wasn't quite as wide.
