Low profile BB Milodon big block pn 31580 oil pan & pickup

Changing around my BB Dart GTS, no pro street - lowering w/ street suspension to handle the curves in Georgia. Would like to find a good low profile Milodon oil pan & pickup (PN 31580).

Just dont want to pay list price, so looking for GC used. Will be pulling out a 7 qt Moroso deep pan & pick-up, so possible trades? or will buy outright.
