The 1986 front motor motor mount sub structure is a stout cast iron piece that may start fracturing from the frame. Fixing consists of just welding up the cracks. On the 87-89 sub structure the thin sheet metal design tends to start cracking at the inner corners just under the front motor mounts. This area is marked by a red line in the pic.



The thick small triangle shape pieces supplied in the 87-89 gusset kit are tacked in place just inside the frame up against the sub structure. This will leave room to leave a nice weld. The sub engine mount gussets reinforce the sub mount to keep it in place as it is subject to twisting and vibration. The twisting of e power full motors easily starts a crack in the sub mount. Weld the crack up and reinforce the sub mount with these small gussets.
