Reply to "eng mounts"

You can try reversing the upper mount-halves; they may have gotten mixed up side-for-side. Note- there are two different upper mounts: one has a single hole, offset from the center of the pad, while the other type has TWO holes. This type can be used in either position- left or right. Finally, you can drill holes in the upper pad to correspond to whatever engine position you'd like- the further back the powertrain is positioned, the more room your engine will have for a big-cap distributor, etc.
Pantera chassis were welded up at the factory on a variety of weld-jigs and not all cars had the engine positioned at the exact same spot. The ZF mount-tabs are thin and flexible and bend easily with a hammer. I reversed our upper engine mounts and bent our 1972 ZF tabs into a shallow 's' shape. This allowed the engine to slide back nearly 3/4" inch from the stock position, so the front sump of the oil pan was not quite touching the crossmember under the engine. It helped considerably in producing an 'almost-flat firewall' access door, for more interior room and the mentioned big distributor cap. See articles in past POCA Newsletters on the subject.
