Oil pans, one year of many that you'll want is the '79' Muatang one that has the dip stick in the pan, many auto stores have them and the pick-up and dipstick.
There's your winner.
The dipstick in the timing cover can't really be used, as the rear sump of the pan is where most of the oil will be.
All Ford cars from '79 onward had the dual sump pan. We are obv talking about ones with SBF engines.
