67 cuda motor mounts

can any body tell me how these mounts are put on the engine,infront or behind the engine mounting lugs the mount can go in about 6 different ways plus ether side.the ony way my hooker headers fit was to put the engine as far back as possible and lifted a half inch or they would sit on the steering linkage right at the idler arm.but now I cant use my mallary dist,the cap hits the wipper motor.any headers fit a 67 barracuda 318 4 speed? sure could use help on this I just cant find anouther car to look at.has any one tryed those high dallar itt headers?
