.............My factory 360 windage trays have the bolt holes wider apart than the factory 340 trays....u could probably slot the holes on either 1...........kim.......
340 windage trays will fit 318 and 273 with 2 hardened washers under the special 340 main bolts. Factory 360 windage trays are different since the main bolts are farther apart. Direct Connection/Mopar Performance trays will fit all, since one side is slotted.
