68 225 into a 63 valiant oil pan and motor mounts

Ok so i am now looking for some parts an advice i am looking for a oil pan for a 225 slant that will fit my 63 valiant. I have found outtheat my slant is out of a 68 dart the oil pans were slightly different from 1960 to 1966 an then changed 67 to .... Not realy sure when . the other thing is the motor mount brackets. I have at least 3 right an 2 left. All are completely Identical. Are there any differences in brackets an mounts or is it all with my oil pan.
