unfortunately you have to change the cross member,remove the
crossmember from the six cylinder fairmont and replace with a
crossmember from a 4 or 8 cylinder faimont or mercury zepher,the
four and eight cylinde crossmembers are exactly the same,then
standard fairmont engine mounts will bolt up. this info is
garunteed 100 percent . as there is nothing about the ford fairmont
that I do not know. had them for 26 years and have done fram up
restorations on 7 of these autos. sincerely MDQ..
