estimated time and cost to replace the oil filter bypass gasket on 1995 Mercury Cougar

I noticed oil leaking "behind" the oil filter and looked at the Mercury service manual and it shows a gasket behind the plate that the oil filter screws onto. looks like two bolts and a stud fasten it to the engine.
