Mine is a 123 body, but I think the engines are the same. It is up front, there is a big frame crossmember that goes across about the middle of the engine. just behind the oilpan is the big frame part. in the middle is a 2(?) piece mount, the top is flat, the bottom is sort of U shaped. the anti dive mount bolts in between these 2 parts, the mounting holes on mine had bushings so that when you tightened it down the 2 rubber blocks were centered in the mount. the other end bolted to the block. basically the thing limits the engine and transmission from pivoting up and down like a pendulum with the transmission as the pivot point.
