There is a plate that holds the oil filter. On that plate you will find the oil sending unit for the stock system. You can remove the stock sending unit and replace with a sending unit for your guage, OR, get a gasket for the plate, remove the plate and drill and tap a hole next to the original sending unit. You will need a 45 deg elbow so that the sender does not hit the CV axle, but I have been runing mine for over 5 years with no problems.
