where to find a 360 magnum center sump pan?

looking for a magnum 360 center sump pan. I know an LA pan will bolt right on but I would like to stay with the one piece pan gasket the magnum uses. I believe the magnums used in trucks and vans were all rear sump, were magnum 360's ever put in cars??(don't think they were) if so what cars? anyway, any info on where to find a center sump magnum 360 pan would sure be helpful.
