Does anyone know for "certain" that the 4.0 liter oil pump from an 01 model S Type will work on the 01 Lincoln LS 3.9 Liter? I have a newly built engine for my LS and Ford has discontinued the oil pump for it. No aftermarket companies make an oil pump for the 3.9 but I have found oil pumps for the 4.0 Liter Jag. If it is a "guaranteed" cross reference, then I know I can move forward and not tear up $3500 worth engine building.

Thanks in advance.
