s/6 to 440 ? engine mounts

I would like to know who has but a 440 into a factory /6.. 66 dart...what mounts were used...I bought a set of trans dapt mounts for this application...sorta.. the pass side works perfect, but the driver side would if the rubber mount was 2'' thicker...plus a little cutting is needed on the k frame to allow room for the oil filter...any thoughts...thinking about making a spacer to put on top of the rubber mount. looks like a 6 cyl mount could work om the driveside its 2'' thick...
