The cable thru the mount is a safety feature incorporated in later mounts to keep the parts from seperating. IIRC you'll either need to drill your engine bracket or snip off the cable. I hope you have a good jack and some stands or blocks to support the engine well. I think it was fairly easy to rock the engine over one side at a time. I seem to remember taking both nuts off the mount, rocking engine, removing old mount, installing new mount, rocking engine back, installing nuts, repeat. WATCH THOSE FINGERS!!
