I need the driveshaft bolts to bolt into the pinion flange. A 7/16 - 4 bolt screwed right in. I have no idea what is supposed to be used since this is a basket case being put back together; but, this is a factory flange. 1986 Ford Mustang 2.3 L 4 cylinder engine. I need these bolts and complete steel brake line assembly. I have nothing at all.
